Hi,
we are an association subdivided into many independent sections and we would like to have one central calendar, which is mostly filled automatically by these several section-calendars.
Each section acts independently and therefore they have their own calendars. Out of these calendars there are some (not all) events which are for interest to the total association and therefore these 'diarizers' should be consolidated into this central calendar. Each single ‚owner‘ of these distributed calendars is responsible for the selection of those events which also should be shown in the central calendar. The section-people are not allowed to service the central calendar manually.
Also the ‚owner‘ of the central calendar should have the possibility to grant or not to grant each single section-calendar bringing in automatically some of their events to this central calendar.

Hopefully the above graphic shows you which function I would like to have.
Sincerely
Wilfried Allé
