AAAHHHhhh !!! Me no like

[root]

I just installed Linux and  decided to use Netscape as it comes with
RedHat. The thing is that I don't like to be called root on newsgroups,
only when I screw up my computer :)
I simply cannot find where to alter this in the preferences, and I've
been looking for quite a while now. Any info would be greatly
appreciated.
Thanks.

root     :)
