subscribe to profiles

I subscribed to my own profile to test it. I am not getting any updates to my email. How does it work?

I mean is that what it does? So when I upload a video, the subscriber will see something in their email? Or is it for the site admin to use the mass mailer to send mail to the subscriber?

You should get an Email notification when a Profile you subscribe to has been edited or has a comment posted.
