I switched to Windows Vista, and it's built in calendar program makes use of ICS, which is a fairly global standard for once! Because of this, I've been playing around with ways to publish and use the calendars...
I have pushed my own personal calendar as well as a calendar for White Dragon Mira Mesa, and found a decent solution to allow people to view those calendars... publicly, it only shows White Dragon (Mira Mesa)'s event calendar, but if you ask me, I can give you info that will let you see my own calendar (a feature probably only 3 people are interested in :) ).
I'm going to find a ton of other ways to annoy people with this stuff now!
Also, if you happen to want to subscribe to either of these calendars via some means that allows ICS subscription, just ask, I can give the link.
