wiki templates (OT)

I'm looking for a good example of how to implement wiki templates (example). (the examples are the grey boxes and yes it's a geeky roleplaying site and yes one of hte templates is a touch broken, but you get the general idea).

Anyone? I know it's OT, but you're all smert geeks and my friends are only about 20% smert geeks (and those friends are mostly on this group anyway).
