1) If there's jokes going about, try to be thick skinned and not take offence
2) If a thread descends into deep discussion, don't post up that "this is boring" - no cares what you think
3) Anything thats even remotely likely to offend anybody has to have the prefix NSFW in the thread title (Not Safe for Work) - automatic ban if you don't
4) If there's a thread on a particular sport going, and you've no interest in it, don't bother posting in it. Start a "Why I think Sport A is shite thread" instead.

All the normal rules still apply obviously
