This one might sound obvious but the rename feature can be an absolute star-feature when used in smart ways. As a host in Zoom you’re able to rename participants in the room and for example put an asterix* behind their name after they’ve shared or took a turn. It’s a great way to keep an overview of who has contributed and who is yet to go.
You can also ask participants to rename themselves according to their team name and/or specific breakout groups they belong to or would like to join. This makes the process of putting people into specific breakouts quick and easy. You can rename participants by opening the ‘participants’ list, click on ‘more’ next to their name, and click ’rename’.
