This is going to sound a stupid question to some people, but I have my reasons.
I'm creating a webserver, using suPHP for each vhost. This way the domains files will be protected from scripting abuse. However I figure each domain is going to need it's own uid/gid. So can a username have special characters in it? i.e. could I have ubersoft.info as a username? Or is this asking for problems?
