I've changed the rewritten url's of the articles again. I noticed that some website (now unfindable of course) that had changed the urls for the articles to include the subject. I've done this also, for now just to see wether the search-engines like this. See links like this one. See the complete archive for a complete list of articles. See 'read more' for details.
Well, it looks like all things are working the way I want them to. I've made some adjustements the last days, most of them hardly visible.
