Ask HN: Which OSS projects needs help?

I'd like to start contributing code/bugfixes to a small to medium sized Python project with an active user base, but am not sure where to start. I know I've come across them, but like a sales drone at Best Buy, when you're actually looking for them, you can't find them.

Ultimately I've found that I use a lot more than I give, and little pet Github projects that only I use aren't really suitable for giving back, as much fun as they are to work on. I'd like to start working _with_ people instead of on my own.

Do you help with or have a project that needs devs?
