From any page in the FitEyes.com blog you are viewing, you will see a "This Blog" area on the right of the page. It looks like the image below.

Click the "Email alerts" link. You will see options similar to those in the image below.

If you are interested in following the blog, I recommend you select the 3rd option from the top ("Send me emails for new posts, articles and comments") and then click "Update Blog Settings."
That's all you need to do. As you see above, you can always unsubscribe later if you change you mind.
Thank you for all the comments you are leaving here! I encourage everyone to comment on each article you read on this site. You have to be signed in to leave comments. If you have any difficulty leaving feedback, contact me (or just send an email to dave using this domain name).
