http://www.mwolson.org/projects/EmacsWiki.html is the page that Michael Olson made for emacs-wiki. For the duration of his maintainership, it may be considered the official emacs-wiki website.
You can join the mailing list at firstname.lastname@example.org using the subscription form at http://mail.nongnu.org/mailman/listinfo/ emacs-wiki-discuss. This mailing list is also available via Gmane (http://gmane.org/). The group is called ‘gmane.emacs.wiki.general’.
http://www.emacswiki.org/cgi-bin/wiki/EmacsWikiMode is the emacswiki.org page, and anyone may add tips and hints to it.
