Again, it just comes down to time - it wouldn't be any good to set up a video in the corner of the room and just leave it running; actually creating a good online course would take a lot of time and manpower, and we have to choose where we focus that. For now, that's on the face-to-face Academy courses as the ones that spread the word most widely and in a most effective format, plus then the free video tutorials for those who don't want to attend.
As with all things Corona though, you never know what the future will bring, and we always keep all suggestions, requests and ideas in mind!
Cheers!
