I signed up for a few months in Yvonnick Prene's site. And actually find it to be really well organized, problem I had was that it felt that my days of practice, at least for a very long time were gonna be scales, and more scales. But I felt lacked the connection with playing the music I wanted to play at least in the beginner's path that I choose there.
Advanced lessons looked really nice and included going really deep with some tunes. Thing was for me that I wanted to do as told and follow the path proposed, but that path wasn't as fun as intended in the early stages.
Now days I'm following the courses at learnjazzstandards.com (LJS), that go from the basics of jazz theory to more advanced concepts, but try to use tunes as way of practicing these concepts as often as possible, and are clearly focused in you polishing a method for learn tunes by yourself applying the given concepts.
Besides that, there's a monthly jazz standard course added to the site, going in great detail on how to tackle the learning process of a given standard. The community includes folks playing all sort of instruments, which is a great value for someone like me, without many musicians around to practice or chat with. I recently went and try the free month trial at Jazz Wire, and is a very similar concept, but a new tune each 3 weeks. It felt somewhat aimed at people with some improvisation skills already, so I'll come back hopefully later on.
While the LJS site has a few harmonica players, it tries to be instrument agnostic, though it has a few courses on the most common jazz instruments (not harmonica) and how to gain chops in those.
All in all, I think at least for me, aiming more at the music that I care to play more than what I can find available "for harmonica" has been a really positive change and lead me to find more people to share my efforts and a clearer path to follow.
