I checked out the GitHub repo. I’m a CPA who’s getting into web development and has some Django experience. Would definitely be interested in contributing.
I think Hordak could really do with a version 2 anyway. There are a number of issues open which I think would make for a big improvement, but would also result in breaking changes. I'm not precious about the codebase either, it hasn't been a priority for me for a while and it would be great to see it given some love (especially from someone with a better knowledge of accounting than I!)
Definitely get in touch if you are interested in being involved. I'd be happy to add you as a maintainer after a pull request or two.
