Okay so, you see the bar where it says "Forum Home, Animal Crossing Wild World, Rules, Shop, What's New, New Posts, Blog Tree, Chat"?
Underneath "Blog Tree" there should be a smaller link that says "Currency". Click on the drop-down arrow and it should say how much TBT you have.
Then click on "Bell" and it should come up with a transaction menu where you can transfer the 50tbt to my account~
I hope that helped lol
