Comment 3 for bug 1202706

You can actually send a notification to every person in a group already, using forums:

1. Create a forum
2. Set it so that all group members are auto-subscribed to the forum
3. Set it so that only admins can post to the forum

Then every time you post to the forum, a "new forum post" notification, containing the text of the forum post, will go out to all the users (and by default, that notification will trigger an email to all of them).

So given that, is there still a use case for sending a "private message" to every member of the group simultaneously?
