Tbt could be used to exchange alot of things throughout the forums like for art, in game things, or even collectible collecting. What do you use it for?
So far I've only used them for the orange collectible and a user title color change so I suppose it'd be collectibles and addons. I've tentatively planned to also use TBT for in-game items that I really can't find myself though.
Mostly art I guess (not lately though), and I buy collectibles sometimes too. Also used a fair bit getting a bunch of the WA and sanrio stuff for my town after I came back to the forums. Oh and it's great for buying Pok?mon codes during one of those distributions so I don't have to go to EB Games and ask for one myself hahah
