How can I set up a Zoom meeting?
After you have signed in, you can set up a meeting. Please refer to the picture.
In the following window you will be presented with several options. Notwithstanding the beginning or end time you provide here, your conference can be started and ended any time.
With the option “Enable join before host”, you are allowing participants to join the meeting before the host has signed-in.
You can find official manuals on the Zoom website. https://support.zoom.us/hc/en-us/articles/201362413-Wie-plane-ich-Meetings
