I just marked you as a moderator. If you go here:
You would see the list of pending messages. (there's none right now) There would be options to approve or reject them. Only reject the messages that are clearly spam, like the "come watch my porno" type. I'd generally let any flex related stuff go through, even if it was a bit off topic.
I get an email whenever there is something to moderate. I'm not sure if I had to turn on a setting, or if it's automatic for moderators.
I'd be happy to get one or two other people just to make sure it stays well covered.
Thanks,
-Marc
