Notify

Notify sends email updates to users on your site and (optionally) posts to Twitter and Facebook. The users can be selected by User Group, and/or by tags specifying user interests. The updates are manual, rather than automatic, so Notify only sends them when you tell it to.

Install with Package Manager.

See the tutorial and documentation at: Bob's Guides.

Notify 1.5.4-pl

Update URL-shortening services

Important: If you use Bitly with Notify to shorten URLS, you need to change the API key as described in the docs.
