The pro forums, are closed forums. So only Pro members can view and respond. In the Pro forums you can be as technical as you want, in the open tech to tech. if it gets too technical, the thread will be moved to a pro forum. Prices are also allowed in the closed forums, but not in tech to tech.
Tech to Tech, is a good place for new members to get their post count up and to aid the membership committee in determining if the applicant is in the trade.
