Looks like only approved members of a social group can post in that social group. Group leaders can approve membership and ban members. Group leaders cannot, however, moderate posts.
I wouldn't be opposed to a movement toward social groups. Anyone want to be a group leader? (Which I assume is a commitment to being online and able to approve members somewhat regularly...)
I'd support a move towards social groups as well, with the hope that everyone who posted their EDD and info in one of those two big threads would be welcome. Its sad, though, because I was really excited about getting the last DDC. Its possible to have more than one group leader as well, right? If we do it, we need to put something regarding civility in the little "purpose statement" thing and be self-regulating. Okay I'm going to get off of here for a while and let others give their two cents.
