This game would be played on GitHub. One person would make a list of some food items, one would make list of some shopping articles, one would make a list of restaurants, and one would make a list of places worth sightseeing. These would be uploaded as a repository in GitHub. And then we shall collaborate.
Basically to use git as a tool and to collaborate in projects. But GitHub gives much more freedom regarding what you do in your account.
I don’t know anything about bitbucket. GitLab is not for me.
Fair enough. :)
Thank you for listening to the suggestions, despite them not working quite right for your current wishes.
Once you get used to Github and what it has to offer, you can get a better idea of how things work!
