Fuji, from The Chronicles of Fuji, commented on my post about the problem with not being able to "subscribe" to comments.
If you're using Blogger, he gave directions on how to add the "subscribe by email" feature. Here are the directions for those of you who might want to add this to your blog so us commenters can see other comments.
Step 1: Go to your blogger settings page.
Step 2: Find the "comments" tab and click on it.
Step 3: Scroll down to the part where it say "Comment Form Placement" and select "Embedded below post".
