Zoom is for “meetings”. One person involved has to set up the meeting, and then send an ID code to everyone else (via phone, text, email, whatever). Everyone else then uses that ID code to join that meeting.
The “meeting” could be a class (in which case it’s probably set up by the teacher), or it could be just friends chatting, and set up by whichever one of them wants to set it up. My extended family had a big Zoom meeting on Easter, set up by one of the cousins who happened to have the paid version (I think that allowed a larger number of people in the meeting-- My family is very large).
My friend is a college professor, so he used the academic license for Zoom to host a Passover seder. But because his license was associated with his class, it appeared in the class schedule and a couple of the TAs crashed the virtual seder.
My friends mostly use Google Hangouts. That only allows about 10 people at a time if you are doing video, though. My family and bridge group have been using Zoom, but if you want to include more than 2 people or more than 40 minutes, someone needs to pay for a license. It’s about $15/month and only one person in the group needs it. Discord is harder to set up, but it’s free and does good video or voice or screen sharing. At work I’m using Microsoft Skype and Teams, but I think those require paid software these days.
If you want something like Zoom but free, where groups of people can gather in the breakout room of their choice (video only in the breakout rooms, text in the entry-way) you could try the MIT media labs (free) Unhangouts. https://unhangout.media.mit.edu/
But it only works with the latest version of Chrome and one other browser (I forget which, but I had a lot of trouble getting into it because I was using an older version of Chrome.)
What’s your goal? Do you just want a place for members of this board to hang out.
I think that was true a few weeks ago, but with so many people using it, they’ve expanded what you can do with the free version. As of April 4th, I had a meeting of an hour and 15 minutes, that I set up using the free version.
