I'm glad my post added some levity to what must be an emotional day for you. I am very close to my mom and often wonder how I will be able to handle losing her. I feel for you.
I put two together to get as close to the old kind of countdown as possible. The first one's from www.tickerfactory.com (lots of choices, but nothing very Disney looking), then I ran a line from http://v50.net right underneath that (more like the old kind of countdown, but it has to be refreshed each time you want to see it change). They were pretty easy to use. Go step by step, and then copy and paste into signature. Hope it goes smoothly for you!
