Shared private calendars.
Create your own groups, or join anothers by entering the group password. then you will see all the calendars for that group, unless they are private.
Groups, calendars and individual calendar entries can be made private and/or locked.
A private and locked group will still allow users to join, as long as they know the group password. A private group will not show up in a search.
No calendars can be created, removed or have its properties modified in a locked group except by the group creator. However calendar entries can still be done by anyone unless the calendar is locked.
Likewise locked entries cannot be removed or modified except by the creator, either of the group, calendar or entry.
So group creators cannot be locked out of either a calendar or an entry.
Users must be added to a private calendar or entry, and only group members can be added.
Group members must enter the group password to join a group, which confirms consent.
This site works on a subscription model, currently $60 per year. For now, you also get a paid account on private-messaging.com as well. That is a tremendous value, I think.
With a paid account, you can create 25 free accounts, limited to only your groups, but have full functionality within your groups. They can pay and upgrade their account to a full account whilst saving all settings and data.
Moderators can be selected for both groups and individual calendars, and these moderators have all the same permissions of the creator.
