There has been a number of spammers registered to this forum lately. Because of that, all new members need to have their first post manually approved. I have not gotten notices for post waiting for approval, nor does a non-approved post trigger the new posts indicator. As a result, when I checked the forum and there was no notices or new posts on the index page, I moved on, failing to approve legitimate posts for new members.
My sincere apologies for everyone affected.
