This 10 minute screencast demos how to set up a simple wiki and blog using ikiwiki.
This is a bit out of date now. The syntax for preprocessor directives has changed. Also, ikiwiki's tutorial explains a more automated way to set up a wiki or blog.
Apologies for the slow typing in places; I did this without a script! (I'm a two finger typist, if you must know. ;-)
