I found this online Gregorian chant academy that I am considering enrolling in. Thought I'd pass it along in case anyone else might also be interested. It appears to be a very recent initiative by the guy who is offering the course, and the course seems comprehensive, dense, and convenient at a reasonable cost. I like that it wouldn't involve travel and can be completed at my own pace.

He has an impressive bio:

He says he's now able to support his family providing chant instruction full-time, so it seems to be going well for him.
