I just took a look at Google Groups 2, and except for some interface ugliness issues and some currently missing features, it's looking pretty neat. It's basically a mix between Yahoo! Groups and the previous Google Groups, with some features that remind me of Gmail, such as the ability to "star" groups for quicker reference.

I already took the time to create the Mystical Winds Google group, which currently has no other members. As I'm not yet familiar with the system, and the system itself isn't quite complete, I'm not sure how to work all of the settings just yet, but I'll figure it out. I already marked my groups to be in Computers > Internet and Computers > Software, but they don't seem to appear there yet. I don't know if that feature just isn't implemented yet or if it needs some sort of approval first.
