do a google search of the newsgroup rec.sport.golf and search for warrior golf.
The gist is, the clubs are ok, but not worth the money, and even though they say there's a money back guarantee, it's very, very hard to get your money back.
The easiest way is to go to the google home page, click on "groups", and either search or browse. You can post from there.
If you plan to really do lots of newsgroup postings, you will want to download a newsreader (forte's free agent is a good one), and point that to an NNTP/news server (you'll have to ask your ISP)
Newsgroups used to kick ***. But web based boards such as this one are prettier and easier to use, so people flock there instead. It thins out the audience a bit. It used to be everyone on the net that wanted to talk about a topic flocked to the newsgroup. Now, you have to do some hunting to find the website that has the best traffic for your favorite topic.
