? re OS X and newsgroups

The good news: My mom got sick of Windows, viruses, etc. and bought a
new iMac. And, even though I'm running 9.1 on an old clone and have
never used OS X before, I've been able to help her (due, in large part,
to the fact that the "intuitive" nature of the Mac OS hasn't really
changed all that much) with things such as setting up her email account,
installing software, and getting her printer/scanner/copier operative.

The bad news: I now want a new Mac and can't afford one!

Anyhow, on to the question: How can I get her set up to read newsgroups?
Can I use the Mail program for that? She's running 10.4.4 with 768 MB
RAM and, IIRC, a 2gHz processor and 160g HD.

TIA,

Karl
