Hi Chuck,
Using Newsgroups can be a bit daunting at first, but it really depends on who your ISP (Internet Service Provider) is and whether or not they have access to binary newsgroups. Newsgroups are essentially giant message boards where people can share information, discussion, and in the case of binary newsgroups, fairly large files.
A good start is the program "Grabit"

It's a program that will let you download (but not post your own) binaries on newsgroups. It's fairly no-nonsense and is pretty easy to use, and it supports yENC (an encoding process, similar to "ZIP").
You will need the following information from your ISP:
Newsgroup server address
login information (if neccessary)
Do a search on your ISP's website for Newsgroups.
If your ISP doesn't support newsgroups, there are a number of Newsreader services for about $10 a month. If you plan on downloading a lot of material, you may want to consider this, since some ISP's put a cap on how much material you can download from a Newsgroup, and the rentention rate is much better with these services (retention is how long a particular message is available on a server before it's erased).
Good luck!
