In your profile you will find a new field for keeping track of how many outings and nights you have spent in your tear.
You can update this as often as you like.
Here's an example: Outings/Nights in Tear: 10/35 (this means 10 outings, 35 nights).
That's right, Sue. A leaving and a coming home makes an outing. That means Jenn still hasn't finished her first one - but she does get a special pin color, so it all works out.
