Group calendars are extremely beneficial, events such as settlements logged in a group calendar can then be viewed by all users.
Rather watch than read? Here's a video about Group Calendars:
1. From the Smokeball home screen select Calendar
2. Select Manage calendars (bottom left of screen)
3. Select Create a new Calendar
4. Name New Calendar, select a colour and save
The New Calendar will then appear under Group Calendars
Events such as settlements can then be allocated to the appropriate group calendar
