Some time ago I've been developing a sharing ideas place where you could just describe your idea and publish it.
Finally I managed to create a github repo and templates for everything right here:
I call it TOBIAS - The Open Bank of Ideas.
So have you had any sport or a game idea in your mind? Something you want to create? You can try to find a teammates for development in right in my TOBIAS repo. Check the Chess concept, for example:
Please let me know what you think about the TOBIAS and Chess concept both here in comments and in the github issues.
