I'm 18, born May 19th 1988... Always found it funny that lbt was in theaters the same year I was born =p
Anyway, I think you shouldn't be ashamed of watching and liking lbt, I don't tell it to everyone, but even if I did most people would be like, "hmm.. and that is...?"
As for writing in forums, I think the earliest age for that would be around 12/13, I only started going to chat rooms and stuff when I was 14, but my computer wasn't that well equiped with internet, I hardly ever touched it, it all changed one day
I stumbled upon the gang of five when I was looking for information about lbt 10 and Ali's possible come back, I sort of stuck around to see how it was, and it's been a nice place to post every once in a while... I don't really know where this post is going so I'm gonna stop it right now :unsure:
