I'm all for seeing how it works out. My one big concern is that since the wiki can be edited by anyone, we all know that at some point, somebody will screw with the list and someone will end up getting removed from the list.
That said, if I end up doing a second group buy, I'm willing to give it a shot once and see how it goes. I'll end up just taking down the user names, sending one group PM and go from there.
As an aside to people hosting, if you take a group of 20 people for a group buy, delete all the usernames so we don't get any overlapping.
For people wanting to get on a group buy, only put your name on the list if you're ready to send funds immediately. If you get a PM saying your bundle is ready but don't respond within two days, the hoster has the right to move on to someone else.
