Lame ti
tle. But, what if we had a page/shop/list/etc. where we could list what we were buying and for how much, and someone with that item/pet/etc. could click on something and poof, sell it to them? But, like, only if the buyer had the tu in their account somewhere. And then, both would get an alert (so the buyer doesn't freak and go 'OMGWHERESMYTUAT?') And it would be editable, so if the buyer was no longer looking for that item, or if they were saving for something, they wouldn't have to deal with having multiples/losing all their goal tu.
I dunno. Just a random thought. Whaddaya say?
