Need Group calendar with 2 functions:
1. Notice board where all can see group events (but not being notified),
2. Possibility to send calendar notification when need to notify the group (of new event or change in it).
It is crutial in case of larger organisation that by default it is #1.
And then when I want to enable it as by default for the group to be auto-notice sending, then I have such option available.
