I think we got sidetracked with discussions of changing the user name,
which was included in my question (and which I've abandoned). What I
would like to know is much simpler.
In the Sharing prefs panel, is it OK to change the computer name and the
rendezvous name to something short and sweet rather than the default,
which is my full name + computer?
Is it safe to assume that I can change it here and no additional changes
will be needed?
