How about an Extropian FAQ that gets posted to the list at least once a month. From reading many of the more controversial postings lately, I get the idea that some posters haven't a clue about the Extropian Principles or even what separates us from other transhumans.
The FAQ could list the principles, give guidelines for postings (using keywords, etc.), and provide other information that newbies to the list could have read at the site's homepage, but are too lazy to do so. It would also give the casual observer more opportunities to have insight as to what we're all about.
One of the problems that I see with moderating a list like ours is the fact that we're all (mostly) a bunch of libertarians (not necessarily members of any party, though) and we're all (mostly) fairly intelligent. Organizing intelligent libertarians is a night-mare in the best of times.
I suggest that we look to Virginia Postrel's "Rules" for a dynamic society and try to implement some of those. I follow this post up with some of her suggestion and everyone can see what we feel about it...

"If you love wealth more than liberty, the tranquility of servitude better than the animating contest of freedom, depart from us in peace. We ask not your counsel nor your arms. Crouch down and lick the hand that feeds you. May your chains rest lightly upon you and may posterity forget that you were our countrymen." --Samuel Adams
