Make sure you have the latest version of the Zoom app installed.

For private webinars, do not release the webinar link and passcode to the public, to people you don’t know or not authorized to participate.

Use your full name (rather than some shady handles) in your Zoom account. It might be compared with an official list of participants.

For moodLearning-supported private webinars for professional training, participants are required to log in (at least 10 minutes before the event) at your designated learning management system (LMS) for check-in prior. Usually the webinar link is provided through the LMS. Further announcements are given or pre-webinar activities (like pre-test) are conducted on the LMS.

Use Zoom’s waiting room to help vet people wanting to participate.

Use no-video, no-mic as default for those who come in for the first time.
