all - I just changed the community settings to moderated membership and posting.
This isn't because I just became a posting nazi, it's because we've been getting weird Russian spam posts every day for the past week or so. Why are they posting to our community when our membership can't even read the posts? who knows. The last one was porn, I guess that's universal.
anyway, I expect the weird Russian spam posters will give up and go away after awhile of being denied. I'll remove the controls and let things go back to being open then. In the meantime, I don't expect to be denying any non-spammer membership or controlling posts other than to weed out spam.
