kind of? from what i understand, tbt is switching servers which will add and take away certain features (such as the blog tree, that’s being removed) but otherwise it’ll still be the same site
^ it's already moved servers, what's changing is the forum software. right now tbt is hosted by vbulletin, but after the move it'll be hosted by xenforo. there isn't going to be a whole new website or anything, just a big update.
