Better to have a look at this: http://www.emacswiki.org/emacs/EmacsMuse
Please Note:
"EmacsMuse is considered to be the eventual replacement for Emacs Wiki Mode. EmacsMuse has been brought to you by JohnWiegley, who is the same guy who made Emacs Wiki Mode. MichaelOlson plans to port over any missing features and functionality from Emacs Wiki to Muse."
