I mean, I'd love it if the wider community got behind my effort and helped me improve it directly, but the important thing is that the material is out there.
Apart from being on a Microsoft service and requiring Microsoft accounts to interact with. At least cloning still works in one direction.
(Love the project, though.)
I was considering mirroring to GitLab, would that help? I'd be open to anything similar as long as it doesn't cause me a whole bunch of extra work :)
