Subscribe to comments w/o commenting

Hi Isabel, may I suggest the following enhancement?

You need to write and send a comment to get your email address in the subscription list. What if one was wishing to stay informed of any new comments, but without posting any comment?

This is a feature you can find in the “Subscribe to Comments Reloaded” extension, for instance.
I used to run this extension until a late evolution that’s not compatible with the theme I’m using (due to the theme not the extension I’m afraid).
That’s why I switched to your extension which I’m glad with, apart this extra-feature. ??

Thanks for reading, hope you’ll take it into account.
