Here's how: after logging onto a blog....look at the URL address bar at the top of the page.....you'll see a RSS icon, usually blue and white on the far right. Click on it. You'll get a pop up menu.....click on RSS. That will open a second window of the blog you are reading....with a menu box on the right. At the bottom of the list of options, you'll see ACTIONS - click on subscribe in mail. That's it.....you'll have a new mailbox in your email program for that blog. At first you may get a bunch of emails....delete the ones you've read and from then on....you'll be the first to know when there's a new post.
On my blog....I've also provided a link you can follow....it's on the right, just below my header. Just click on the blue text and follow the instructions above.
See ya soon!
