I have put up a service that shows the changes made to the wiki in the last 24 hours. 'It runs every day at 11:15 am CET'. You can look at it at http://pascal.scheffers.net/wikidiff/ but I'd like to put it right here in the wiki if that is possible. For that, the wikit would need some extra formatting rules to make use of the different colours.

Source of the wikidiff software is at http://pascal.scheffers.net/wikidiff/wikidiff.tcl.txt

Right now it just parses the cvs-diffs of the day before and dumps those into a page 
(which uses a slightly added to wiki.css, so it looks the same as the wiki!). Comments please.
