I checked and corrected all submitted wishlists so far. Please let me know if you sent your wish list and your name in the google document is green and not blue. Still 23 wish lists open!

I fixed the error - sorry

It is in the very first post:

Today I got the last regrouping info. PLEASE, before you start to create your want list, CHECK YOUR COINS AND GROUPS! Now we come to the want list submission phase. Again I would like to quote Chucks explanations, because they are so good that even I understood it the first time Before I start a general WARNING: the biggest mistake that happens from time to time is that the people don't use the coin number but the Excel row number! It is your fault when you get for example for a mou10bike just a regular coin that still can be bought for 12$!!! Use ONLY the numbers out of the column "REFER TO THIS COLUMN ONLY!" PLEASE TRY TO USE THE SAME SYNTAX (no commas or semicolons between the numbers) as it will cost me additional work to correct that. Now you can send this list in an email to: mathtrade10@web.de There is one issue that I haven't discussed yet: How to prevent receiving the same coin more than once. This will be explained in the next post...

Great story!

Just in case you haven't seen this star wars unicorns Find all information about this project here: Link

Because that is the ONE and ONLY coin in the whole list :laughing I have no idea but I corrected it.

No grouping for me

WE HAVE A NEW RECORD: 1563 coins have been listed, unbelievable! Oficially the submission phase is closed (if you want to submit more coins let me know as soon as possible). I copied the submission sheet into the sheet called "USE THIS COIN SHEET", sorted all coins and give them numbers. PLEASE CHECK ALL YOUR COINS!!!!!!" (A lot of people worked with the document and there may be some unwanted errors) Now the Regroup Phase begins (the Regroup Phase will be open until next Sunday January 9th, 9:00) What is regrouping about? Again I want to use Chuck's explanations: To regroup your offers or to let me know that you don't do any regrouping, please - send an email to: mathtrade10@web.de - send a PN on Facebook to Thomas Weide - or post here or in the German FB-Coin-Group containing the line numbers and the coin descriptions of all coins for each coin set you want to create. Also mention your geocaching.com nickname -- just as an extra measure of insurance to keep me from making mistakes. Please use the ID's as listed on the USE THIS COIN SHEET worksheet in the Mathtrade11 document. Make sure you only use the numbers in the column titled "REFER TO THIS COLUMN ONLY!" To make the group coins more visible I will highlight the rows of them with light yellow color. I will also highlight all User Names green when they submitted the regrouping information and blue when they submitted the want list (will start next week)- Please let me know if you have any questions about this process. You can post your questions here, or email them.

Happy New Year to all I extended the coin submission phase by one day, so please enter your coins untill Sunday evening Have a great time Thomas

Unbelievable but true: I managed to get all 4 of my last top 4 list. Now I have just a top 2 list: - Neptunes Compass Tsun Edition - Ready for the Fourth - San Francisco

Ülease remember that you have to add your coins untill 2nd of January

I agree to what Murazer said. In general it is not a problem at all. You could also list all three because the rules just said, you should TRY to limit your coins to maximum 50. But if you definetely just want to trade one of these three, it is the best to list just one coin with the addition of "your choice". Just make sure, that the word "set" doesn't lead to misunderstandings.

Still time to sign in. So far we have 53 participants out of 8 countries. Already 403 coins have been listed.

47 particpants and all have gotten an Invitation to the spread sheet. If you haven't received a mail, please let me know.

I've sent an invitation to all who registered up to now. We have 40 participants from 7 different countries so far: USA, Spain, Australia, Netherlands, Canada, Poland and Germany

I've sent an invitation to the Google spreadsheet to everybody, who signed in so far. Please let me know if you didn't get a mail. Up to now we have 23 participants from 6 different countries

Thanks for the great race, Gary! Beside some dipping my racer #8 just went into 4 caches but travelled about 2800 miles - not too bad I think!

(Most of the following text was written by E&Cplus3 in earlier mathtrades and just slightly changed, thank you Chuck!). Ok, here we go! Sign in this 12th International Mathtrade by sending your info to mathtrade10@web.de (this is not a mistake, I just want to use this email address, that I've generated before) I will need your: - Caching Name - Real Name - FULL Mailing Address (including Country!) - Email Address - if you don't want me to send your address to all participants, please mention this (up to now I had only sent out the addresses to the participants that are needed, but this took hours without having fun) I will then send you the Link to the Google spreadsheet in which you can submit your coins! If you don't get an email within 3 days just let me know. The trade will be divided into four phases: 1. Coin submission - entering your trade offers into the spreadsheet (ends January 2nd) 2. Regroup - reorganize your coin submissions to create groups (ends January 9th or earlier) 3. Want list submission - create your wish lists! (ends February 6th or earlier) 4. Trading! - trade list generated and emailed to you (starts February 8th if all goes well!) Please respect the following rules: 1. This is an international trade - only take part in it if you are willing to pay for a possible overseas shipment of your coins! Remember that in theory each coin that you trade away may have to be sent to a different destination, within or outside of your own country. 2. You can list both trackable and non-trackable coins. If nothing is mentioned in the Remarks column, the coin will be assumed to be trackable and unactivated. In all other cases the status of the coin needs to be specified in the Remarks column. Activated coins are only allowed if they will be offered up for adoption (with the exception of Lackey and Moun10bike coins, obviously ). 3. Participants may only submit one coin of any one edition (same coin with same finish/colour/etc) to trade. Duplicates are not allowed. 4. Please make sure you adhere to the deadlines shown above! Any edit after a deadline will be ignored! 5. Please try to keep your list to 50 coins or less! Keep an eye on this thread - I will use it to post additional information/clarifications whenever needed! Of course you can also use it to post any questions or remarks. A More Detailed Explanation: Q. What is a geocoin math trade? What makes it different from a 'normal' trade? A. In a ' normal' trade, person A gives coin X to person B and person B give coin Y to person A. Sometimes person A wants a coin that person B has, but has nothing that interests person B to give in return. In that case person A could go looking for a person C to arrange a trade to get a coin from person's B want list. In a math trade you don't have to hunt for a 'person C' -- the software will do this for you! The math trade software will find optimal 'trade chains', some of which may involve just the regular 2 coins, while other 'trade chains' that are part of the same math trade may involve 3, 4, 5 or even more coins. Q. I feel uncomfortable listing coin offers without knowing what I'll receive in return for them. Why would I do this? A. You will be the one to decide what you'll get in return. After everyone has listed their coin offers, you can go through the total list of offers and make a want list for every coin you have offered. If you are not interested in trading one of your coins for any of the listed offers, you will simply use an empty want list for it, so that your coin won't be traded at all. Q. What if someone offers a coin that I REALLY want? Is there a way that I can maybe offer 2 of my coins in exchange for this coveted coin? A. Yes, there is. After Phase 1 (entering coin offers), we will enter Phase 2 (regrouping). During this phase you have a chance to look closely at the coins that are being offered, and if there are coins you would really want to get, you could try and create a more interesting offer by grouping two or more of your coins into one offer. If you group coin X and Y together, then these will not be traded separately, but as one single unit, for which you can decide (during the want list submission phase) what you want to trade them for. (Detailed instructions for this regrouping will follow once we hit that phase (but don't worry, it's actually quite simple). Q. Two or more people have listed one specific coin that I like. But if I include both in my want lists for, say, two of my coins, I risk ending up with 2 copies of the same coin. Is there a way to prevent this? A. Yes, there is (a more verbose answer will follow at the appropriate time).

Yeahh, the Google guys are ok with my age, the next mathtrade will be started in a few minutes...

We've been trading all this time ... and NOW you tell us you are underage ... ??? ... or are they verifying that you may be TOO OLD ... ??? ************************* Well, good question, but everything is relativ. In my eyes I'm too young and in the eyes of my kids I'm too old. Let's hope the Google guys think that my age is right

Ok, obviously there is enough interest. Right now I'm waiting for an age verification of Google Docs and then I will start the 12th international mathtrade. See you Thomas

If there is enough interest in another international mathtrade I would start one in December, so coin submission could end beginning of January, regrouping till middle of January and the results could be end of January at the latest.

Any reason, why it was sent back to you?
