Klaatu:

I just tried that on the user account I could best afford to lose. It 
worked. I can still log into it, but now it's visible in Users and Groups.

Now: I know how to move that dummy user "out of the way" temporarily, to 
make room for my main user account. (I'd probably want to log in as 
someone else when I did that.) But: how do I vest "administrative 
privileges" in an existing user? And how do I modify a group? Is 
"groupmod" the appropriate command?

Thanks in advance.
