I hope you like the Live Groups better than I do, Bugs.
I created one for my group, just to reserve the name
more than anything else because it's nothing more (IMHO)
than a glorified blog.
Please warn your membership to be careful of what
email they use to join because it will be visible to all.
You also can't create other boards or do custom pages
like you can at MSN groups, by the way, at least not any
way I can see.
