I'm not sure how long this one will last, and I'd rather not give Gav reason to shut it down, so here are a few ground rules:
1) Stay in the joking/teasing realm. Think of the sort of stuff you'd say to a friend when you just want to give them a bit of a hard time.
2) Keep it relatively clean and family friendly, just like everything else.
3) Keep it clever and witty. "RITFencing sucks and is dumb." isn't going to make anyone laugh. "RITFencing's posts are so dumb, my IQ drops by osmosis when I read them." is a bit better.
And yes, I know I'm really leaving myself wide open by starting this.
