Clearspace has Private Messages that allow users in the system to send messages among each other within the application. It can also be configured so that when a user gets a Private Message in the system, an email is sent to them to notify them of it.
Unfortunately, there is not a way to send a Private Message to a group. It can be sent to multiple users but they would need to be entered individually.
If you want to enable Private Messages, you need to go to the admin console under System -> Settings -> Private Messages and set Private Messages enabled. You can also configure whether users will get email notification about Private Messages in this screen. Also, you need to enable the permission to create Private Messages at the root Space by going to Spaces -> Permissions -> Space Permissions in the Admin console and checking the permission to allow "Private Message" for the appropriate users/groups.
Thanks. I've entered this as a feature request on the other site.
We also need the group communication in our site.
Can you please let me know if this feature is already implemented or the release number it is due in ?
