Hi!
First of all, I use Firefox with Sage, I prefer this one to Wizz Reader.
With Sage all you have to do is add an .XML file a site is providing to your bookmarks in SAGE folders and you're subscribed to RSS Channel.
RSS is just a file with information. An XML file to be exact. If you add a file like this to your RSS Reader - your Reader will just check if the file is getting updated with new information and it reads this file, thus giving you information.
It's like a REAL ONLINE newsletter, but you don't have to give your email address.
I put some info about RSS on my page at
www.hitrss.com as well. It's for RSS publishers, but you as a reader may find some info useful as well.
Greetings,
- Michael
