Feel free to join any of the open community meetings and/or events listed on the Sakai Project or Apereo Project Calendars. Most working groups have regular meeting times, and there are also a number of ad hoc meetings and events.
Meetings are typically conducted online via Big Blue Button, courtesy of Blindside Networks (an Apereo commercial affiliate).
There are also several community conferences and events held each year, providing additional opportunities to connect with other Sakai users.
