Letting your community and the rest of the Yearly Meeting know what events are coming up is a good way to start a conversation.
The event calendar which appears on the right side of every web site is shared by the entire community. What you add to the calendar will be seen by every Meeting and every Committee.
For each event it is recommended that you first create an associated post describing the event: what it is, where it is, when it is: all the details. Normally you are restricted to two or three lines on the event calendar – so those lines should be links to this more complete description.
See the comments below for more pointers.
