Wondering if a course for newcomers on properly setting up & securing a reliable & tightly-secured alt to Zoom might be interesting. Geared to those wanting larger calls (50-150) or many concurrent calls, & with more Zoom-alike features than Jitsi offers.
The official BigBlueButton installation method is a breeze, but even so I see many deploying on bad bones: no disk encryption for recordings & db, no disk redundancy, poor security on their tunnel, no backup/restore strategy++
