I just self-certified as a #PSF "Contributing Member". "Contributing Members are people who dedicate at least five hours per month volunteering on Python-related projects that advance the mission of the PSF. Python-related projects can be open-source software projects using #Python that you contribute to, Python user groups / conferences you organize, etc."
I plan to mostly work on #MicroPython, for which I do not receive or seek compensation. Multiply that 60 hours a year by a fair hourly rate and it well out-strips the small monetary donation I also made. Yes, it doesn't move the needle on ensuring the PSF is adequately funded, but writing software for the common good is something I've long been passionate about.
