Used for general communication.
We have both a Facebook members group and a Messenger group chat that are used for general communication and discussion. The Facebook Group is mainly used to distribute information and Zoom links for upcoming meetings, which can be found on other channels too. The Messenger chat is mostly used for quick updates and questions and general chat about upcoming things.
You can request to join the Facebook Group at the link above, and message one of the admins there if you want to join the Messenger group.
