Lol larger forums are definatly worse, and as a young student i'm a member of LOADS lol for allsorts of different things. I've recently joined a student one and there are much worse arguments going on there and you wouldnt know where to start, they have a thread for everything and anything.
I'm also part of a reptile forum and they whinge and whinge and are really difficult to explain simple things to, like why you cant steal someones dog just because you think its right
Those are my biggest two forums at the moment. The student one is massive though and hugely international, and if u think i'm an opinionated student you shout meet some of them lol. I'm quiet on forums compared to some of them!
