I have successfully been able to create the .newsrc file if it does not already exist, as well as see all the newsgroups available on a given news server.
How can you access a .newsrc file in a user's home directory to see what newsgroups are subscribed to? And when you subscribe to a newsgroup on a NNTP server does it automatically save this information for you in the .newsrc file ? Also the NNTP protocols specify any newsgroup on a server not subscribed to will have an exclamation mark(!) at the end of the name (ie. news.newusers.questions!) if not subscribed to, and a colon( if subscribed to. All the newsgroups I see have colons and not exclamation marks.
