I am very pleased to announce a very nice upgrade to the robotic surgery blog.
I have installed a plugin that allows users who make comments to blog entries to subscribe to that entry.

You can then receive an email if someone else makes additional comments.

You will get an email to confirm that you did indeed, sign up for the entry and can easily cancel the subscription to the entry with each reminder.

Thanks to gruntdoc for introducing me to this feature from everitz.
