News and Blog subscriptions for end users

I saw post in the forum somewhere where the person asked about allowing the user to subscribe to the Blog as a hole, not the comments. I would like to do something like this for both Blogs and News, i.e. allow the user to receive notifications whenever a new blog post or news item is published. 

Hi Jacques,

In my mind i have this solution:

1) Crete something to store list emails, which subscribed to blogs or news (in can be dynamic module, form, or something else)

2) Subscribe to IDataEvent and then send notification to all this emails
