I have. ;)
We're talking about the Secret Santa Christmas Swap 2008. I joined last year, and I had the most fun ever! planning and sneaking, waiting and, well, feeling a lot like a little kid again - eager to see what my "victim" thought, and (im)patiently waiting for my swap to arrive.
So why don't you hop on over to Chookyblue (or just click on the image above) and sign up too?
