Let me get this straight.
Today, the French Wikipedia replaced its official logo with a "logo" made of a bunch of flowers, which you designed, which makes no mention of Wikipedia at all, bears no resemblance to the regular logo, and which commemorates the significant event of "the end of spring."
Shortly after announcing this important event on IRC, you unilaterally remove the logo from the research pages (including [[m:Research]], which is not associated with the Network), and then complain to the mailing list about a voluntary association of individuals designing their own logo for internal use.
Is that about right?
As I have explained before, the logo does *not* stand only for the research network. It can be used by anyone in the context of Wikimedia research. At least one individual has put it on their user page, and Jakob Voss put it on the general research page. It does not mention the network at all.
If the issue is that it incorporates parts of the Wikimedia logo design, I'm willing to design a logo that doesn't do so. Everything else should be up to the people working on this project.
