I'm thinking sort of like on steam, you know how even if someone is offline, you can drop a trade request with your items for their items. I think it would be cool. Opinions?

uhm of course it would be on the forum. also it seems really neat to have.

It would just be like a PM.

"So and So would like to trade his <item here> for your <item here>.

And maybe there would be a button that says "Would you like to make this offer? Yes or No"

Whichever one you click, another Pop up should happen and ask to make sure you're certian about it.

Actually yeah... I haven't done a safe trade before. That's basiclally exactly what this is. Wtf
