This is my opinion of course, but putting up a paywall would be a bad idea, and I see it doing more harm than good, it would be like cutting off your nose to spite your face, I really cant seeing even half of the current user base paying to access this site, reason being, everything here, can be found on elsewhere for free, namely other forums and Facebook and all the modeling groups. The only thing that forums have over Facebook is threads that keep the info easier to find. If you went to a paywall, you would need to provide content that can not be found anywhere else to make it worth while , of course, strictly my opinion. My suggestion is this, many forums have the availability for their members to contribute to the forum, one forum I am on has it set up as yearly thing, and they offer a private area only for paid members , and everyone that takes contributions has a little bar underneath the users avatar that shows that have contributed to the forum. Food for thought.
