newsgroups

[Boyoboy]

just how are you supposed to find newsgroups that you want with mozilla? 
  i tried a long time ago, but could never figure it out and it crashed 
every other second.  now that mozilla is more stable with mail and news 
i thought i'd give it a try, hoping they had changed it, but haven't. 
so how to i find a newsgroup if i don't know the full name to begin 
with?  the only reason i have this ng listed is because it was already 
in my communicator profile.
