Pruning a few members would fix 75% of the problems on TBN. Repeat offenders. A short list of members.
As someone mentioned, a quick Google search will find an endless list of forums. Every subject you can think of has forums geared toward it.
I'm a member of a forum that evolved thru what's going on here. Had thousands of posts per day. Excellent forum geared toward that particular subject. Trolls took over. The Administration let them rule too long before running them off. Destroyed the forums daily post counts.
That forum is clawing it's way back out of the swamp. No attitudes, just discussion and sharing information. It will take years, if ever, for it to get back where it was. Good contributors moved on.
