Adventures in F,O, X, & 0

My health is not the best. Two and a half years ago I was diagnosed with myeloma after finding myself suddenly very breathless when doing strenuous exercise.

I still think the concept was sound - but it did require a full-on "funnel" process to get in a steady flow of new participants, and there was quite a bit of infrastructure needed to get it fully automated. However, late last year I got a bit of a "rude awakening" from a doctor regarding my health - and so I've "pivoted" to simply providing the course as a not-for-profit service.
