Most of those engaged in the enormous group spanking of the wonderful Addy have known her much longer than I. But even as a relative newcomer, I'm overjoyed to have the privilege to be part of that crew.
Happy birthday, Addy! Here's a smack from me! (You know, of course, that I could provide something much more severe, but I think I'd better not, seeing as you have so very many smacks coming!)
