Wikimedia is migrating its license from GFDL to CC-BY-SA, under a clause
in the latest GFDL allowing colalborative sites to do this. Have you
considered making the same change?
Under the terms of the license, any site wishing to do so must migrate by
August 1 of this year. Since Wikimedia's migration means that partner site
will no longer be compatible with Wikipedia content, I am writing to major
GFDL wikis to be sure they are informed about it.
If you wish, you can follow our outreach efforts here:
