Really?
Which zone are we in now?
Looks like we are in Zone 2.
The rules say trolling and thread hijacking are not allowed. This gets violated regularly, seemingly without consequence.
The rules for Zone 2 don't mention personal attacks... which is the root of the problem.
If this were changed, and personal attacks were banned... it remains to be seen if the new rule would be enforced any better than the rules against trolling and thread hijacking are enforced (which is very little).
If personal attacks were made illegal, and if this rule (and all others) were rigorously and fairly enforced, then I believe the forum would improve over the course of some months, and stay improved.
Some offenders would change their ways. Other would get suspended, and a few would get eventually kicked out. And people who have avoided this place (I can name many) would start coming back... which would add to the improvement.
No forum will ever be perfect. But this one could use a LOT of improvement.
