E-mail Notifications for IndiSpire Topics?

I see some interesting topics in indiSpire. I submitted my first post for this activity today. But I wonder how I missed it all these days.

Is it possible to create a button that will enable us to 'follow' indiSpire topics via email as they are announced, without visiting the indiBlogger homepage? It will also be helpful if we can follow the posts for that topic, by email, as they are posted.

Might increase the participation and engagement. Just a suggestion for a new feature.
