I have also started using Zoom for my players. We started a new campaign with 7 players plus myself and the video conferencing of Zoom allows all eight of us to be onscreen together at the same time. Zoom goes fast enough that we do not find ourselves talking over one another due to lag, which is a godsend.
Since one of my players already has it for work we have the $15 per month subscription available to us, which means more than 40 minutes of playtime, as also has the shareable whiteboard to use.
Do the players need to have a subscription? I just got a license myself, and I was thinking I could just schedule a meeting 1/week, and they would download the software for the meeting each time...
