Hi Alan,

I think:
   1) the wiki page that now lists install & runtime errors should be  
split up in separate install & runtime error pages.
   2) the pages should get an index like http://wiki.apache.org/couchdb/Frequently_asked_questions 
  that adds #anchors for direct links.

Anybody wants to tackle this? Be our hero!

Cheers
Jan
