the rules are pretty simple, no super commons, no discosomas, rics are acceptable. uncommons, semi-rare, even rare if you wish to send it, polyps count must be at least 5, and the coral must be able with hold up to USPS priority mailing. its basicly a way for pweople to share uncommon stuff without spending lots of money, you ship 2x once to the person your getting the thermos from and once to send the thermos onward, so it works out to 2 (or more) semirare corals for about 20$ in my case scopus was very generous and sent several frags instead of just one because he did not know what I already had, this is not needed or expected and it should be known that you may get something you already have, this has happened to me before with the freinds I usually blind trade with. you ca chose to ship faster at your own cost, dont expect the reciever to pay thats the idea everyone ships out at their expense.
its worked good so far but this not hearing anything from rhyno-nm has me worried. so far no one has bailed. hopefully its just a matter of losing internet connection or something like that.
