I'm 22, been around since I was 15... The oldest member I remember seeing around for more than a few posts was in their 50s, if I recall correctly. I certainly can't tell you who the hell that was, though, it's been at least a few years since they've been on (I think...). Ah, ZU senility - it kicks in so much earlier than the real stuff. <3
Well, I'm 14 now (soon 15 ^^), but I think I'm not too childish. I find there are a lot of "old" people here - over 18, too. Just look at the "more serious" thread, and you'll see the intelligence of old people.
