To create a new meeting link/dial-in:
Anyone with a GEFD email account can create a meeting.
To create a meeting link/dial-in, simply go to meet.google.com, log in with your GEFD account, and click "new meeting."
You will be able to choose whether to start a meeting immediately or, alternatively, create a meeting link and dial-in to distribute for a future meeting.
Once created, the link will continue to work indefinitely (for instance, we always use the same link for our monthly meeting).
To open/join a meeting:
Once the meeting is created, dial-in users can join at any time.
To use the web interface, at least one person with a GEFD account must join the meeting with their GEFD login.
Any person logged in with a GEFD account can immediately join any meeting for which they have the link, but others using the web interface will be put in a waiting room and must be admitted to the meeting by a GEFD user who is already in the meeting.
