Rick - I voted no, not to restrict.
I can certainly see both ways on this issue, kinda tough.
1). I can see your point on those who may consistently receive, but give nothing (or very little). There are a lot of members here who give, give, and give more ... to anyone at any time. Loads of great folks on here and this is why OFC is basically the only forum I participate in and visit regularly.
2). On the other hand, if we block parts of the posts from visitors, or may I say 'potential members', would that drive them away ? If you would access this forum, only to see things blocked out, could you really get a sense of what we're all about ? Seeing the posts, reports, pics, and such ... maybe that would get some folks excited about joining up and becoming active. Not sure, maybe this would only reflect a very small percentage of the visitors. Even so, by becoming a member, that does not imply an active role in the board.
Tough question Rick ... you're making me thing to hard at this hour. Probably good and bad points on both sides of the question. The more I read, and re-read, and re-read my item number 2 above, maybe I should have voted for members only with a minimum number of posts. Yeah ... I should have voted for members only with a minimum number of posts. My head hurts now.
