Currently our policies do not allow the use of logos of organizations we are collaborating with, even with permission from these organizations, in the non mainspace areas of Wikipedia where we are collaborating.
As this use "with permission" is legal, it is not in mainspace, and it promotes the development of Wikipedia I have started a RfC here https://en.wikipedia.org/wiki/Wikipedia_talk:Non-free_content#Logos_of_organ... that we allow it. Thoughts?
