I can't say for sure what it entails - and maybe it's only the first post by a new user that gets held up.

However, after I composed a lengthy post a couple weeks back with flatbed questions - I was greeted with a message when submitting that said it wouldn't show up until a moderator approved it.

After waiting over a week, I sent a PM to Tom - no response, and the post is still not visible. I gave up and searched/asked questions elsewhere.

I've no idea why I'm able to post here now. Maybe the restriction was only in the forum I posted in, maybe it's only for new posts (not replies)...who knows.
