My article about MediaWiki for the German Linux-Magazin has now been
translated into English:
http://www.linux-magazine.com/issue/42/Mediawiki.pdf
Keep in mind that the pre-final of this article was finished on Jan 22. I
sent them a few updates but it doesn't describe the in-place installer
yet. Nevertheless the installation procedure as described should still
work.
Regards,
Erik
