When my family was visiting this past summer, we went geocaching with their GPS (before I had one) and found 2 caches and didn't find one. I was curious today if anyone else had found that one, but I couldn't find a way to look at caches I didn't find, only the ones I found. Is this feature availabe? And if so, how?

I got an email from another user that was sent through geocaching.com. I couldn't find a way to email the person back. Can anyone help me?
