Guests cannot post. What you can is probably guests trying to post? I don't know? All I know is that we havent any posts by guests, except where members have posted and then left the forum.
It really is just hidden users showing up as guest in the list. That's how the SMF software deals with it, you mods just don't see it because users aren't hidden from you.
Well I can see guests posting at times althought they can't.
