I still do check that other forum (club) once in a great while, but I think this BoaterEd Carver forum is still the best. Still may not have the highest traffic in the world, but almost every discussion and post is interesting to me. Still the most helpful. I wouldn't mind $50 and I would gladly pay it, but I'm not inclined to pay $50 if I'm not allowed to see anything before I buy. I wouldn't buy a car or a boat sight unseen, and I'm not inclined to buy a forum membership that way either. I run a couple websites myself so I understand the time and overhead involved, but I just find that up front payment requirement mildly annoying.
I'm also a member of the Bayliners Owners Club (we still own a little Capri just for kicks) but that site is so noisy that I just can't keep up and it loses my interest. To me this one has real value, practical and otherwise, even if it is pretty quiet.
