pman626,
First, welcome to Flyertalk.
Second, the system is set up to moderate SOME posts of new users... certain key words can trigger the rule.... as well as links in early posts. I have a feeling that is what caught your post... your photo in your picture. Too often, we have spammers who try a hit and run, so the rules are in place to provide a better viewing experience for our members.
Usually, posts get approved pretty quickly by the respective forum mods. If you ever find a post you made is not showing, just message that forums' moderator... and they will look into it.
Again, thanks for joining our community and look forward to your continued participation.
