This is how to subscribe to a blog feed in Windows Internet Explorer 7. I tried to do this in a video but it looks awful when posted on Blogger, so I just took screenshots:
Step 1: Click on the RSS Feed button on the toolbar shown below, and click "ORUG-MEP-RSS".

Step 2: Click "Subscribe to this feed".

Step 3. Click "Subscribe"

Step 4: The ORUG-MEP feed is added to your feeds list. Click "View my feeds" to see the list.

Step 5: Whenever the name of the feed is in bold, it means the feed has been updated. You can add any other blog feeds to your feeds list using the same method.

To access your feeds list you can click the star button (Favorites) then click on the Feeds tab.
