I joined both .com and .co.uk in the last couple of weeks and have posted in both.
I am already bored to death of people on .com arguing with each other about a mod called Fraz.
I also get the impression that there are little groups of people on both forums who just seem to chat to each other and pretty much ignore anyone else.
Maybe I just joined at a bad time but as it stands i'm likely to get fed up of both forums pretty quickly. Sorry.
