Additionally, the Wiki should be hosted within the x.org or freedesktop.org
domains to ensure the relevance of the URLs down the road.

The Wiki and FAQ need to be created of course before this can receive
closure.  Please update when things are in the state where FAQ items
can be added, and I will try to contribute some entries, either directly
to the wiki, or via bugzilla or email, whichever is preferred.

The Wiki can be hosted anywhere as long as the pointers are correct.
If the pointers are on a DNS we control we can always change them
when things are moved.

Sorry, I think I was a bit confusing above.  What I meant to say, is that
it looks much more professional if the support materials and URLs referenced
in the official documentation, are URLs that are within the freedesktop.org
or x.org domains.  Those can redirect to elsewhere, or whatnot, but it just
looks more professional having x.org FAQ/support/etc. with an x.org URL,
rather than pointing to some other website.

The actual data can be hosted wherever it is convenient of course.  An error
message something like:

"A fatal error has occured, which may be caused due to a bug, or
 misconfiguration, blah blah blah....  before reporting a bug, please read the
 troubleshooting FAQ located at http://support.x.org blah blah blah"

Or wiki.x.org, or some other URL that looks "official".  That URL can then
redirect to another website, or can have DNS pointing wherever happens to
be convenient.  This way it allows the site to easily move around if
necessary, and just looks more professional IMHO.

Also, the above message content is just an example, not intended to
reflect what the exact message should say.  ;o)

Remaining issue: redirect of wiki.x.org to freedesktop.org.

Keith has just done this.
