I created and removed several single letter emails as part of a test once, and I made several short names (mine, spam@, etc). The biggest problem was that too short would take the backend down because it received more mail than could be indexes at the time so too short or too common would get deleted to protect the system. As far as I know Randal still has his though. :-)

But yea your right about the plus I guess Ii didn't read it detailed enough.
