Sorry to keep bringing it up, but if not zOMG, then where?
Towns will not work, as 1) there are scripters, which poses a security risk, and 2) Those of you who were at the casual meeting we had a few months ago will remember how bad it is, and Towns hasn't been updated since then.
Our options for meeting locations are as follows:
Towns (listed above)
Rally (same vulnerability as Towns)
Skittles
Virtual Hollywood
zOMG (Barton Town would work if you're worried about not being able to get to Old Aquaduct)
And really, zOMG makes the most sense, since there's already a "GiB" presense there, real or not.
Obviously, I'm in favor of zOMG, but there aren't really many other options, unless you just want to have it forum-based.
