I may take on a collaborator or two in future, start a discussion if interested, and show me what you can do.

Ugh... I can code stuff. Fix some minor bugs. Yk

I'm not sure what I need to be able to do in order to be a worthy collaborator in your opinion.

I'm not sure either tbh, maybe submit a pull request on Github? It would be pretty neat if we could get a few new items or features that aren't just 'MK+ item'. If things go well I'm open to inviting you to be an official collaborator. Feel free to open a discussion on Git or the forums if you want to discuss ideas, PMs are fine too.
