When I was watching ZP episodes, I would see the recent comments and want to say something, but I had no account. So I got an account.
That, and this is the first forum I've seen that actually had interesting things to talk about, didn't have abusive admins that would ban you for a misspelling, and it's not full of preteens that haven't figured out how to spell complete words yet or how not to type in all caps. The last forum I was on was full of people posting threads that said like, "OMG!? LOL IM BOARD THT SUCKS!!ROFL"
