I frequently help some non-profit organization on a voluntary basis, just to help their causes, although I don't belong to any volunteer association officially.
Among other things, I recently realized an artistic page for the website of a non-profit organization focused on LGBT rights. It might be used for a promotional campaign. For it's online and my name it's mentioned, might it include on my Linkedin profile?
If yes, how should I do that?
I cannot include it in the section "Organizations" for I don't belong to any volunteer association officially: is there any other way to show it?
