This was posted at about 5:37 AM on Fri 18 Jan 2008, to see if signing in with BlogAlert will work. I used the signup form on that page, and if it does work, there is a widget available that can be added to my blog.
The claim is: updates are delivered daily. I did the sign-up and clicked on the confirmation link at about 5:32. Good luck!
P.S. Used the front email address for this first test. Should use another to test if add widget. Should also investigate how easy it is to unsubscribe.
P.P.S. Entered the URL corresponding to the feed icon in the location bar when I signed up: http://bjkeefe-test.blogspot.com/feeds/posts/default
If that doesn't work, go back and try: http://bjkeefe-test.blogspot.com/atom.xml
