Several announcement channels

[FBalduin]

current solution: one group can create/edit/delete announcements. The other user read all announcements from this group.

Maybe there is a better solution:
Several announcement groups with different rights.
e.g. Group: "Global Announcements": see current solution,
group: "Team A": just the announcements of users in this group.

Maybe that can be solved a seperate app and the dashboard use this app...
