>>you may want to try a "free" news server so you'll be able to read the newsgroups from a dedicated newsreader like Outlook Express or Netscape (or whatever). Just email this address: firstname.lastname@example.org and ask them for an account. Include your name and email address and they'll send you an ID and password.
