After you create a news account, I think it'd be a nice idea if you get a dialog that asked you if you'd like to see the list of groups available. Perhaps: "Would you like to see a list of groups available to this account?" "'news.mozilla.org' account created, would you like to see the newsgroups associated with this server?"
I'll search to see if we have this filed already.
