feature suggestion for subscribe by email

I was playing around and modding my wp admin bar, checked out wordpres.com and I see they provide a simply link to subscribe to a blog!

now I realize this plugin is geared towards people inputting their name and email, but how about adding a mod to it so logged in peeps can subscribe via a simple button or link?

this way I could show the link in the admin bar to logged in users only :slight_smile:
