Who made that recommendation?
All the seasoned folks I speak with. Typically, newbies tend to misunderstand the intent of the reviewers' notes. They also tend to think they're above the guidelines and think they can get away with something. Then when they're caught, they misconstrue the intent and the tone and make themselves look like the victim when in truth, they open their mouths by posting here and tend to look like the back end of an animal instead of looking at the cause for concern and doing something constructive about it.
For the record, the reviewers do not subscribe to this theory. I have recommended that a new cacher find a few caches first (2-3) but never anything like a year or 100 caches. But we are taking this thread off topic.
I just recently de-lurked after reading for about year. We have found 31 caches and have hidden 3. Our reviewer was extremely nice and one even sped up the process because he wasn't sure why one was on hold. We are new at this, but I don't think it's being new that makes a person take a comment the wrong way, it's the person...AND you can never really know what a person means in this format, it's not like you are talking to them directly! I always type out a response and take a step back before sending.....it's all about perception!
As for waiting to place a cache, as long as you know what you are doing, and follow the guidlines, why should you have to wait a year? Where I'm from, I can find most of the local ones in a year, and if everyone waited to do that, there wouldn't be very many new ones to find!
This is just my 2 cents, but everyone I have come into contact with, whether it be cachers, admins, or reviewers have been very polite and kind. No complaints here!
