I think jpbarr sent the coin once around the world to himself again

Email sent! Sounds like a big fun!

I've received your email and sent you the invitation to the spreadsheet. 38 math traders have registered so far so it's going to be a huge list

I have no idea why some were able to enter their coins and some not (you were not the only one!) I changed the setting of the document and hope it works now. Please let me know if you still have problems.

I've just sent an invitation to all who registered so far. If you haven't received any email, please let me know. It is truly an international math trade. We have 30 math traders so far (from Germany, USA, Canada, Spain, Poland, Australia, Netherlands)

I've sent an invitation to the Google spreadsheet to all who registered so far Neal, I haven't received an email from you so far!

Ok, the 11th international math trade is officially started: 11th Mathtrade

(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 11th 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 generated last year) I will need your: - Caching Name - Real Name - FULL Mailing Address (including Country!) - Email Address 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 March 29th) 2. Regroup - reorganize your coin submissions to create groups (ends April 5th or earlier) 3. Want list submission - create your wish lists! (ends May 2nd or earlier) 4. Trading! - trade list generated and emailed to you (starts May 4th 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).

Let us know in this thread when you will start the new one I don't come that often on the forum, except to take care of my missions, so I don't want to miss anything Just ask the mod'd to change the topic that way it will stay right here Yes, I could do that, but I think it would be good to have an explanation of the mathtrade and the time schedule as the first post so nobody has to search for it. So I hope it is ok to start a new thread and announce it here. By the way, I hope it is ok for you, Chuck, when I use all the explanations, that you wrote in earlier mathtrades?!

Wow, 37 participants so far. That is indeed enough interest I will prepare everything and start a new thread when everything is finished. So get your traders ready!

Who would be interested in another mathtrade? If there is enough interest I could start it for example beginning of March and it could end sometime in May.

Wow, congratulationto this awesome coin

Remeber jpbarr, if you can't fullfill a wish, there is, according to the rules of this mission,an alternative: :)

There is a presale for a new coin: FLUX Capacitor. There are 3 versions: - Original Edition: Satin Silver / white LED / Travel to date: Oct 21 2015 (neon orange) - 1st Geocache LE: Satin Gold / yellow LED / Travel to date: May 03 2000 (neon bright red) - Custom Edition: Satin Silver / blue LED / Travel to date: your own choice! (neon green) Link to presale: presale Description taken from the web site mygeocoin.de: About this coin: Do these quotes ring a bell? ... Lorraine Baines: Well, that is your name, isn't it? Calvin Klein? It's written all over your underwear. ~~~ Dr. Emmett Brown: Then tell me, future boy, who's President of the United States in 1985? Marty McFly: Ronald Reagan. Dr. Emmett Brown: Ronald Reagan? The actor? ~~~ Younger Dr. Emmett Brown: [running out of the room] 1.21 gigawatts! 1.21 gigawatts. Great Scott! Yes, it's THE movie of my childhood: Back to the future! 30 years ago Marty and Doc Brown decided to travel to the future and they arrived on October, 21st 2015. I still remember that I thought "I will be old at that time". (Of course I am not old now! ) On the one hand this coin gives me food for thought, on the other hand I am very happy about the memories with VHS tapes and birthday parties when we were allowed to watch this movie in the livingroom-cinema. Maybe you are on the same wavelength like me and Carsten (glider74) who gave the inspiration for this coin and who still dreams of his own flux capacitor ;-)
