As far as regional forums, and moderators in general, I am trying to lay low. Rules, well, same idea. I think that censoring information, even bad information, just ain't my thing. Granted if something goes up that is questionable in a legal sense (meaning *I* might be sued) then it's going to get chopped, no questions asked. But for the most part people are pretty good here. The RS club really seems to be the spill over of many of the original I-club members and so far 99.9% of the posts have been mature, adult, and either fun or informative. Therefore I have seen no need to moderate or place rules on anything.
As far as regional posts, I really think that's like an off-topic place for people to go. Most regional forums I have used were so small that it was easy to sort through the messages that were goofy vs. those that were informational. So again, no moderation needed.
I think there are enough members to warrant regional forums. Remember that as people join they will naturally gravitate toward their regional forum and those areas will quickly become the busiest. They certainly are on that other club.
