Dude,
If everyone worked off the same google calendar for F18, you can specify who can add events, invite others, and then ITS UP TO THEM TO UPDATE THE CALENDAR. No more herding cats, and real accountability if the event never gets posted. Additionally, the HTML is right on the seetings in google so you can just paste it so that it appears on your website's calendar (and looks like your calendar) Capeesh?
BTW, YOU (Dan Delave) can already post to the "northeastern Catamaran Events" calendar. Try it! Its tooooo easy.
