I think you have to show good faith by first only commenting. I also think you can't post pictures until you are 'accepted', too.
I quit this forum three years ago because it sucked, and I don't know how I managed to get back on it. I got an email about something so I clicked on it, and found I was back in. I'm going to quit, again. I wish we could delete our accounts but they won't allow that because it messes the threads up if you have posts or comments in it. So, once again, I'm going to log out and forget it.
