Subscription to newsgroup?

[a little prince]

   Hi,

   I recently joined this unix-wizards discussion list.
   And I have a question.
   Is there any way that I can subscribe various usenet newsgroups
   like comp.sources or comp.lang  etc on BITNET?
   If any, is it possible that I should join one or more newgroups
   simultaneously?
   Thanks in advance.

                           Sincerely,
