There is no right or wrong answer here.... but I've found very little discussion on this topic. As I was just checking in a document that I plan on sharing with someone I thought... "What is the best way to tag this version of this doc as something meaningful?" Checkin comments, labels, some other variable that can be cannibalized? I found a thread here: Searching by Label
But that didn't have too much information on labels either. I'm just curious if anyone has tried using labels and found it to be a successful venture?
