We've just added a new feature to the calendar.
When you are creating a new event in the calendar you can turn on the option of having members click a link to indicate their attendance.
When you create the event, just check the box at the bottom of the screen that says, "Allow users to specify that they will attending this event."
That will put a link in the post that users can click on. When they do, their username gets added to a list in the post.
See the entry for this year's MOPARfest as an example:
