So you've got plenty of experience in fandom, since 3 or 4. XD

I've never managed to get myself into a different fandom. HP is pretty much my life. For a while though I flirted with RPS, Manic Street Preachers. :D Mostly as a joke, sort of, writing silly fics with a friend privately back and forth. It was fun!

But yes, there's so much in HP to keep one busy. ;)
