I gave up on trading for awhile because the Pound board is all UCs, all the time, but recently (don't know how recently, I was gone awhile), I discovered PAHs and Shuffles. I think it's super interesting how the players have invented games within games.
Pet Auction House - a no pass "game" where you put up a (usually converted) pet and users bid on it.
Shuffle - usually UC, has a bunch of variations, pass, no-pass, etc. You list your pet and everyone and their brother bids on it.
Personal Pet Auction - basically you take bids on your pet for x number of hours, then accept a bid at the end.
I ask because I see WAY more trades happen with PAH and Shuffle than I do in watching the boards. Wondering what you all think of this, and if you've tried either.
