Finally was able to find a friend who was inactive for over 100 days last year and then was removed from my friendslist because of it. They also left all the guilds they were in that I knew of (or possibly got kicked for inactivity). But this update was the only way I was ever going to be able to find them short of them becoming active again. So I sent them an offline message and they got a notification and came online today. It was really great being able to reconnect with my old friend this way.
