It brings a post to the admin's attention in case it's spam, racist, or against the site TOS, etc.
Thanks. I enable invitation, since I want to keep the topics to be high quality.
I think what Sonia was asking about how posts can be put into the moderation queue. By stop words, user age/post count, Ip address, a kismet score.
@yariplus Thanks, got your idea!
users = logged in users
guests = non logged in users
total = users + guests
connections = number of socket connections open (usually equal to tabs open to your forum)
@Pixel Note that only Administrators can see the flag reasons, not the moderators who don't got access to the ACP.
