I posted two posts, one yesterday at about 3 am? maybe? somewhere around there. And the other about 15 minutes ago. They both said that they would not post until reviewed by a moderator, and the one from yesterday has not shown up yet?
Apologies for that - the message is a generic one - ie, you post may not appear straight away - but it does look like a couple got caught by the anti-spam script (which filters posts by new members until they have 10 posts), but I've unmoderated those posts now.
