Hi Fred: I've uploaded an iCal (.ics) file to our page on the Wiki,
which I would like to keep updated as we add activities to our
Software Freedom Day event. The filename should stay the same, so
that when I upload a new file people will simply see the new events
appear in their calendars. Unfortunately, I'm not allowed to overwrite
files with the same name. Is it possible to remove that restriction?

Thanx,
--Bob.
