Update from Al... in early 2021, the Google Meet Attendance extension was purchased by another organization and I am no longer involved with the project... sorry, I am not allowed to discuss the details any further than that.
Support questions should now be sent to [email protected].
Rest assured this was not an easy decision for me. I truly appreciate all of the encouragement and support I receieved as this project grew over the past year. Thanks! Take care and stay safe.
