We will be able to change the license to GFDL v2, when
it is released.
And after that, it may be relicensed to a new GNU Wiki license, which
will hopefully be better suited for Wikis. But we have to rely on the
good sense of the FSF for that...
I don't know what kind of changes are proposed, but there must be
fairly limited if it's going to be compatible with the current
license.
