Thanks for getting this out there, draino!
I kicked off the influx of Pull Requests with committing all of the coding for the TS Sealed League, which has been probably the biggest community-related project over the course of this year.
From here I'll be scanning the code where known bugs are present and, when possible, working with TheGaffer to get his opinion on my proposed fixes.
We can try to solicit for more people to be on the gemp coding task force as well
From there I can put together all of the fixes into PRs which would be easy for MarcinS to implement.
So far that's just my broad plan of action to help in my own capacity, though organizing, facilitating, and managing. I'm not a coding expert either
Since a lot of people are too busy to commit fully, I think if it's approached with a team of people who will contribute when they can, we can make a solid impact.
