The new arrangement didn't incense me all that much, but one thing I would like to point out:
If you're not a member of The Meeting Hall, it's not visible to you. Meaning, there are probably a number of people (and especially new users) who are unaware of its existence.
An important element in debate is diversity. It's fine to screen people (especially to remove the useless ones) but perhaps it makes more sense to screen people OUT rather than in. Personally, I think it would make more sense to give everyone access to this particular forum by default, then pluck the troublesome users from it. I know I was a reader and member on HLP for a few months before I ever ventured into the old "Hard Light" forum. I'd hate to see new and intelligent positions excluded from a debates folder simply because they aren't aware of it.
Take it for what it's worth, but I think a policy of inclusiveness that plucks problematic members is probably a better way of organizing a debates folder than a policy of exclusiveness to begin with. It scares me that this folder may end up a hiding ground for a bunch of the maturer fellows around here to ramble on in some elitist club.
Just my $0.02 - $0.08 CAD (accounting for the exchange rate
