*sniff* This is good (no, great) news, but you will be sorely missed by us. Truthfully, you are/were the best co-worker I've ever had (same goes for Mark) and that isn't a new revelation - it's always been so.

As Snook says, you are moving closer to your true passion and I'm proud of your accomplishments, as both a friend and a team member.

Congratulations and good luck.
