In order to participate Zoom sessions, even as a user, you will need to download the Zoom application to your computer or other device. Make sure you're on the right site use link above.
After the application is downloaded (which takes only a few seconds), you'll need to open (click on) the .exe file and go through the installation procedure. You'll have to create an ID and password, but you'll need only the most basic free service and should not pay for anything as a user.
An email link will be send to you each week for joining the meetings.
