If you'd like a Neopets-focused active trading site, http://metaplode.com/forum/forum.php?referrerid=83 is a good place to start. It's a derivative of another very popular Neopets cheating forum, GamingGutter. But GG's gone down, so MP is now taking its place, run by many of the same members of GG.

Put down Leet as the guy who referred you and then PM me on there. You'll get a shell from my list, either an attic shell or 4 month+.

Cheers!
