Relicensing wiki.mozilla.org to CC-BY-SA

A few years ago, we made the five-year effort to relicense the Mozilla 
codebase under the current tri-license so that our code could be used in 
more contexts and circumstances, without losing copyleft. This has been 
very successful, enabling projects like Songbird and Miro to happen 
which otherwise couldn't due to licensing incompatibilities.

We'd now plan to do another similar, if smaller, thing. The Mozilla 
project, and the world, has been moving towards Creative Commons 
licences for non-code content. This is the licence used by the Mozilla 
Developer Centre and by www.mozilla.org. However, anomalously, 
wiki.mozilla.org is currently under the GNU FDL (Free Documentation 
Licence). This is for no other reason than it was the MediaWiki default 
at the time we set it up, and we inadvertently neglected to change it.

The GNU Project have generously added a relicensing clause to the most 
recent version of the FDL, 1.3, to allow FDL wikis to relicense under 
Creative Commons CC-BY-SA. wiki.mozilla.org is eligible to use this 
exception. We plan to use it to make our wiki content solely CC-BY-SA, 
and so interoperable with MDC, www.mozilla.org and the vast body of 
other Creative Commons-licensed content around the world. We believe 
that this is consistent with contributors' expectations based on their 
experience with other Mozilla sites, and it will simplify moving 
wiki.mozilla.org content to other such sites and remixing it with
content on those sites.

We want to be sure that people are OK with this, so if you have an 
objection, please post it in mozilla.legal.
