Cake from a mix?

Having read the positive feedback on Seattle Bon Vivant for the Williams Sonoma bundt mixes, I've decided to use the Pumpkin I got as a birthday gift a few weeks ago. I'm going to use the pumpkin-shaped bundt cake pan that they make as well, though as I plan to serve it to quite a few people, I may not assemble it in all its pumpkin-shaped glory for ease of slicing. Half-pumpkin shaped glory? Doesn't quite have the same ring.
