Nelson asked:
3. Is there a good mediawiki book that I can find
examples for basic (e.g.
creating a page, edit a page, setting directory & files permissions, how
to incorporate an extension...) operations? Of course if there is a
comprehensive list of mediawiki commands (I mean .php files) and their
usages will be even better.
I'm not sure of the quality, but there is at least one MediaWiki book that you
can get on Amazon:
MediaWiki Administrators' Tutorial Guide: Install, manage, and customize your
MediaWiki installation (Paperback - Mar 22, 2007)
