RSS Mailer : "RSS Mailer emails the contents of RSS feeds to mailing list users. You can manage your users and RSS feeds through a web interface and send a selected number of items from your RSS feeds (individually or all together) to the email addresses on your mail list. Users can subscribe/unsubscribe themselves through forms, or the administrator can subscribe/unsubscribe them through the web interface."

If you aren't using Blogware (I hear that there are a few of you that haven't switched yet) you should check out RSS Mailer. This offers almost identical functionality as Blogware's "Email Notifications" feature to blogging packages like MT, Radio and the like.

The good folk over at CitizenLab continue to do good things!
