It's also worth reading the man page for passwd(5), in
particular the following partial paragraph:

     The login name must never begin with a hyphen (``-'');
     also, it is strongly suggested that neither upper-case
     characters nor dots (``.'') be part of the name, as this
     tends to confuse mailers.

And then ask yourself if you really *need* to use this kind of
login or if it's just something you'd like.  If you don't really
need it (and there must be very few reasons why you might), you
would probably be better off not to do it.
