Quite right, it might be a lot easier to ask for help than to draw a line.

I would also agree that removing this forum would only push the traffic you're trying to regulate to one of the other two.

Maybe it is time to consider an overhaul of the whole ETS forum area. If it's unmanagable in it's present form, there are other options that would be easier to monitor, manage, and still provide the sort of public outreach as was originally intended.

In the end it is still up to you my friend. Your solicitation for our opinions is appreciated, but it is still your call to make.
