As part of the planned release of the English Wikipedia's "Version 1.0" release, one editor had created a logo for the project based on the Wikipedia globe, which would constitute a derivative work. I recently found out that the logo, found at http://en.wikipedia.org/wiki/Image:WP1_0_Icon.png, was "released" under the GFDL. As this is not possible due to the Foundation's policy, after consulting with Anthere, I changed the copyright of the image to point to the Foundation, as done in the Wikipedia logo page.
I'd like to know if this is enough to transfer ownership of the image to the Foundation, or if there is something left to be done. We might need another derivative logo for a planned test release, dubbed "Wikipedia 0.5" for now, so I would also like to know if doing so would be possible, if it became necessary for the responsible editorial team to do so.
Sincerely,
Titoxd.
