On naming — we will be, as much as we are able, harshly enforcing naming conventions as outlined in the guidelines. You can’t register as someone famous, or a name which is close to someone famous or easily confused with someone famous, unless you are that famous person.
On tech support — we cannot offer tech support on user logins right now. If you’re having problems, let us know, of course, but there’s no 24-hour service level agreement with this any more than if you found yourself in the moderation queue because you’re out of AOL.
