Can amateurs join

I am part of a committee of volunteer AV techs at a large senior residence. We handle typically 15 events per month, lectures, concerts, or showing movies. A couple of venues are casual, where we roll in a portable sound system so presenters can use hand mics, and a portable 70" TV so they can show their powerpoints. Our main venue is a nice auditorium with a stage, roll-down screen and projector (soon to be upgraded to 4K). A complication is that since Covid, it's become expected by the community that auditorium events will also be on zoom so people can watch from their apartments. To that end we use Zoom Room hardware, but the setup gets complicated to give a good experience both in the room and remotely.
