different licenses,
Nobody hinders one to state on ones user-page that every contribution of
that user is dual-licenced, as long as the second-licence is compatible
to GFDL.
Correction: Practically almost all licenses are _incompatible_ with the
GFDL, including the various CC licenses. If the licenses were
compatible, there would be no need to explicitly state so, although it
might be a good idea. Rather, we allow people to license their
contributions under _any license_ because it is _their_ work, not ours.
They just have to agree to include the GFDL among the licenses they
release their work under.
