Rated 5 out of 5 stars

I love this add on and have used it for a couple of years. It is invaluable. I noticed that a few people have noted a problem I just had, not being able to add/modify an entry nor respond to alerts. Somehow, my calendar was locked and changed to read only. Once I unchecked read only, everything worked just fine. I hope this helps some people. Thank you for a wonderful add on.

This review is for a previous version of the add-on (0.8).
