A calendar on your page?

What do you think of a calendar on everyone's "your page" page? I could show on that calendar the days and times I'm available to climb. If a climbing event is agreed upon by two climbers, then that event would show up on both of their calendars.

Just seems like a more formal way to do what MP already supports through the forums to connect climbing partners, but there could be other advantages to it, I suppose.

I would suspect that calendar data requires much less space than all the picture data that MP already stores.

It sounds like a great idea, as long as it was kept really simple and super easy to use.
