We've been testing Jitsi for video chat because of the unlimited time that it offers compared to Zoom. Here are a few tricks we've noticed so far:

• You don't need to download anything since Jitsi runs straight from the browser.
• However, it seems to be pretty CPU-hungry. It might be a good idea to close all other programs while running Jitsi.
• Using headphones instead of the laptop's speaker helps reduce feedback for others.

• In your browser, type the URL we emailed you and enter the password when prompted.
• Before joining the meeting, enter your name and callsign, and put yourself on mute.
  

• You can download the Jitsi app instead of using the browser.
• We've notice some devices create a lot of feedback when using the device's speakers so headphones are a must.

• Put yourself on mute when you're not talking to reduce the background noise / feedback.
