When we set up his MacPro (he's a switcher) - he put my mom as the user, first & last name - but did her short name as her nickname. Now they can't create an account with that nickname. Their concern is that having her first & last name as the Admin account - and if she goes online, that anyone on the net can see that name. Hence, she wants her account to be her nickname. I told him only if he lets Little Snitch send it.... But seriously, i've never THOUGHT about it, because I assumed that the outside world can't see my user account name. So the question is striking me as weird.... So help please!!!
