In an effort to fight spam we have implemented a post moderation system.

When you register for the PTF you will initially be placed into a 'Moderated' group. For your first 5 posts and PM's (private messages) you will have to pass a CAPTCHA. Your first 5 posts will also be held for moderator approval.

Once you have made 5 posts, and they have been approved, you will be moved to the PTF Newbie group and you will no longer have to pass the CAPTCHA or have your posts approved.

Hopefully this will help combat the spam.
