Thanks! Not quite a forehead slapper, but clearer in hindsight! I did 
have logout (but of course, was logged in as admin while doing this) but 
had ?q=user instead of user/login. With the zillion lines of code I've 
seen in my years, I'm still often humbled by the simplicity that results 
from the design, like here. Magical.
