Well, having been a member of the old site for many years and then discovering this one, I have been disappointed in the lack of traffic here. The old board was one kick-ass site and I don't really know why this one hasn't taken off like a raped date. Maybe, as the OP posted, it's due to the moderation. But I think it must be more than that. Maybe the old board was just dead for too long and people went elsewhere.
A while back a moderator wrote that he was enforcing a rule that a member would need a minimum number of posts before being granted access to the Classifieds, in an attempt to stimulate general discussions and user traffic. I'm not sure if any particular liability attaches to a website operator whose primary traffic involves firearm sales and trades, but I would imagine not. I think sales and trades were the lifeblood of the "old" site and I know I bought and sold lots of guns there over the years. Maybe changing the rule and not requiring a minimum number of posts might generate more classifieds traffic; I don't know. I'm just thinking out loud as a member who would like to see this site do better.
This time of night I am also on prescription morphine for pain and my thoughts can get a little scrambled.
