Over the last several years, I've been educated, befriended, and entertained here. But it was only recently that I started paying attention to the signatures of the members, some of which are extremely clever. My favorite up this point is "If it ain't broke, . . fix it until it is." Unfortunately, the site's search function doesn't include sigs, so I can't credit the appropriate member (though I will if I stumble across it again).
So, for now, my nomination for best AVS sig is Rhetor, "I love deadlines. I like the whooshing sound they make as they fly by! --Douglas Adams"
Anyone else have a favorite?
