Haven't been here in a while

Yes, it is, indeed, a very different interface but all of the old discussions are still here, although the Interests way of sorting them has disappeared. You may find my guide to the menu system useful: I think that you'll find, after just exploring the site for a little, that it is very logically arranged and easy to find your way around. You should also take time to read the new Community Guidelines, which can be found under "Help" in the little box with your username and avatar. You should also note that since the earnings program ended, some of the rules have been relaxed somewhat.
