There are a lot of people with a great deal to offer who continue to lurk because they can't be bothered with post count status games.
"Newbie" does not equate inexperienced, simply someone who does not habitually post on boards. Of late there has been a noticeable lack of fresh perspective, diversity in opinion and new information on PM simply because it is often so unfriendly to outsiders.
A high post count is much an indicator of an unfavorable influence on the boards signal to noise ratio as of "contribution". If your volume of "me to" posting drowns out useful dialog then you would be better off lurking.
Bodybuilding is very much an intellectual property game. You want people to openly post hard-won knowledge then judge them by the content of their posts not their quantity.
New posters are more often then not greeted with open hostility regardless of the content of their posts. That's the way you want to run the board so be it, but it greatly limits the information that will be shared with you.
