nicknames in newsgroup ( netscape 4.7 )

[Ron de Wijs]

Until recently I connected to newsgroups under Windows and with Outlook
Express. At this moment I am running Unix and Netscape. Many people in
several newsgroups know me under my nickname but in Netscape I can't
seem to find where to configure it so that it will be seen under
'sender' ...
Anyone can help me out with this ?
