[Mediawiki-l] Mediawiki license

[Paul Scruby]

Hiya,

What are the terms of the licensing for mediawiki?  I would like to use a
wiki to document some private projects.  I do not wish to change the
mediawiki source-code or redistribute my own version of it so I am happy
to use it under the terms of the GPL.  However, I am confused because the
'edit' tab of my new wiki states that anything contributed to my wiki is
under the terms of the GFDL.  Are the licensing terms of mediawiki
different from other GPL programs, eg using Open Office to write
commercial documents, or emacs to write proprietary programs?

In otherwords do the GFDL terms of mediawiki's license apply to all any
content that is added any mediawiki wiki, or is this statement included
for mediawiki's in the public domain such as wikimedia's wikipedia?

Many thanks,

Paul
