Yeah, I know, we're here to get away from the rules. Bear with me here, I'll make this brief.
Keep the forum safe for work, image-wise. By this, I mean have some consideration for the slackers amongst us... instead of hotlinking that image of you fornicating with a sheep, link it and note that it is "NSFW" (Not Safe For Work). Tagging a thread as NSFW will meet this requirement.

and

smilies are also an appropriate way to indicate "NSFW" content.
Don't reveal someone else's personal information. Just keep it reasonable. Call someone by their first name? Not really an issue. Post their credit card number? Too far.
New rules can be added at the staff's discretion.
Staff may respond to specific incidents not covered by these rules as required.
You may use whatever language you feel is appropriate.
To give you an idea of how I envision this forum being moderated: aside from correcting minor things like changing a questionable hotlink to a URL, very little.
