Q: While, I'm probably not really knowledgeable enough to contribute much if anything to your github project, What else or how else could others maybe help with it? (apart from code or content)
A: General feedback about from a user's perspective. And for those who don't have time to edit the .md files and submit pull requests: there's a ticket where links can just be pasted in. All that's required is a GitHub account for that. I also have an email address displayed on the README for those who don't have a GitHub account and choose not to get one.
Anyone is also welcome to join the chat in the Slack Workspace. There are different channels set up for development, help using git, #random for any type of chat, and a #music channel. People can participate in the chat, or observe how things are done, the process for developing a project.
There's a channel to suggest links for the KB, or discuss if links aren't suitable. For instance, if they are too indirectly related to mental health, or have too much advertising.
So far there haven't been any substantial discussions about the content of the links in the KB, no arguments or philosophical debates. And that's how I think this project would best operate. People of course have strong views on this subject; and for some it's more personal than others. And there's a Code of Conduct to help make things especially clear.
And of course, every project needs document editors. :)
