I like all of the sub-forums in the Gaming section. I enjoy talking about games, so it suits me well. I go into the forum games sub-forum occasionally to play some forum games, but I haven't been in there lately because I don't have much time for it. Aside from those four sub-forum, I'd say Popular Media. I like to have conversations about music, movies, television, etc..
I'm basically in Popular Media all the time now. I used to love The Tavern but it's full of topics that I find really boring now so I don't bother posting on it.
