For most of our members, their calendar - whether it's iCal, Google, Outlook, etc. - is where their life resides. I want them to be able to add our events to their calendar no matter where they are reading about them. Even "Registering" for an event is essentially meaningless if that event registration isn't being instantly added to their calendar whichever one they use.

I see the "Add to my calendar" feature on the Event Details page, which seems to work great. But I'd like to propose that you add that same other feature in a few other places as well:

1) Event emails. This seems like the most obvious -- we send our members an email telling them about an event, I want them to be able to add it to their own calendars right then and there, whether it's a "Registered" event or not. Just embedding that same Add to my calendar widget would be good enough as a beta solution.

2) Events page. For many of our events, especially those that don't require registration, this is the page where my members are more likely to interface with the event itself. It's also where they see several of our events at once -- I want them to be able to easily add all of our events to their calendar without navigating back and forth to each individual Event Details page. There's plenty of white space to stick that feature -- perhaps directly to the left of "Show details >>" Would be great to have an "Add" button on each event in Calendar View too.

3) Event Registration: When a member registers for one of my events, ideally they would be proactively prompted with a pop-up or something that actively suggests they add that event to their own calendar, which is where they're most likely to remind themselves on the day. Would really help to cut down on No-Shows.
