[reboot]

It means that if you have a program such as Thunderbird email client that can pick up news feeds, you can subcribe using that url and Free Republic postings will show up in you email program as they are posted. Great for reading blogs too.

What in means, in over simplified terms, is the feed is like saying send me a notice whenever something new is added.

If your email client automatically checks your mail every few minutes you will have the pleasure of a "chime" continuously and your in-box will be full forever. Not a good idea if you don't have a hugh amount of space in your in-box. The effect is the same as being mailbombed, hundreds or thousands of emails at once. You machine may freeze for a few minutes or lock up until you reboot. Be judicious when you set this up, you may find that you have been FReeped.

Thanks for the info, Lucky you I'm choosing to ask since
(I think) I kind of I understood your post.

All FR postings or can you just choose certain key words?

If that's the case it sounds cool, but if it's all FR postings then maybe[pretty likey]I'm missing something, but that doesn't sound like it accomplishes anything except reproducing every FR link in my email box and filling it up too.
