I have to give it to these guys (I work on a competitor product). Even though this is a simple idea and possibly something of trivial implementation, it's clear, honest, and just plain nice. My hat is off to them for keeping their customers happy - very well done.
I don't want to pee on anyone's parade - I honestly don't - so I would hate to link to it here, even though it's "competition". I'll link to it on my profile instead.
(Never imagined me writing this, actually, but I think it makes sense. I truly do admire these folks for this particular project - I wish I had thought of it myself, I'll tell you that)
