There was another thread sort of like this before, but it was pretty specific just on fanfic: here.

But to answer your question, I have a whole slew of TV shows I'm into, but I'm not in any of the fandoms. I used to be really involved in the Buffy and Roswell fandoms. I'm such a sci-fi/fantasy girl.

But aside from this one, there only one fandom I'm really heavily involved in and that's Twilight.

Edit: Lisa, your avatar is awesome!

Thanks to Cat for my rockin' avatar!

Perry: Son, you just hit the bulls eye. It's like we're supporting characters in some TV show and it's only about them.
Jimmy: Yeah! It's like all we do is advance their plots.
Perry: To tell you the truth, I'm sick of it.
Jimmy: Man, me too!
