yogsloth: I don't know about that. I just made a 58-for-1 trade. :)
58-for-1 trade is quite extreme. I had a 10-for-1 and a 8-for-1 trade on Groupees as well though. I think it's the result of people not understanding how the trade system on Groupees works. When you offer various games for a trade, the other side can't choose which game(s) he wants, but have to accept them all or decline the trade offer. There's also no PM sytem to talk to the other side and make an offer.
