Idea #4421: Leadership Code of Conduct should be signed by Team Leaders

Browsing for project references, I stumbled upon the Leadership Code of Conduct page, on Ubuntu website
http://www.ubuntu.com/community/leadership-conduct

I found this page and its advices very interesting, but I was disappointed not to be able to sign it, as a Project Leader.

I think that, at least, information about this code of conduct should be displayed more obviously for team leaders (since we know who is owner of a team, it shouldn't be hard to display a note on Leadership CoC) ; and these team leaders could be encouraged to sign it, and stick to it.
