Here's some information to help you with scheduling zoom meetings:

When scheduling a meeting, make sure to scroll to the 'meeting options' section and click on the box that says 'automatically record meeting' if you do NOT want it to be recorded. (The default is set to automatically record for some reason)

You can also turn off the waiting room if you do not want to have to admit people into your meeting when they log in. Scroll to the 'security' section, and click on the 'meeting room' box, which will turn it off, participants will then automatically join the meeting when they sign in.

There also is an option to create 'breakout rooms' now.  If for whatever reason 2 meetings are scheduled at the same time, you can assign a group of people into a separate space for a time.
