Welcome aBoard, emcc.
I am going to put on my curmudgeon cap yet again and suggest that this topic be discussed where it belongs, in the underused Weekly Themes section.

Having said that, my favorite AWAD theme was the one that featured the five vowels in reverse order... but I'll ask tsuwm to locate that bit of ancient history, since he is researcher hor concours & nonpareil. He's also pretty good at digging up stuff.
