Why on earth are you trying to use a Wiki as a calendaring app whn there are so many good calendaring apps out there. I'm fairly techie - but if someone told me to edit a Wiki to put my holidays in, I would not be amused.
You'll be getting them to use vi to enter expenses claims next.
I agree here. A Wiki does not seem to be a good base for a 'holiday booking' tool. Of course, personally, I've always been a fan of Lotus Notes for being able to adapt applications like this to the normal workflow of an office.
