...you should sign up to get 40% off of your upgrade exam to Windows Server 2008. Do I sound too pushy? You don't have to. But all you have to do is sign in with your Live ID to register, then you'll get an e-mail with your voucher code that will work at any test center worldwide. Then, you can use it if you want when the WS2003-->2008 upgrade exams come out (one for MCSAs and one for MCSEs) or not, if you don't feel like it.
Note: the only people who care about this are those who hold an MCSA or MCSE on Windows Server 2003, because they are the only people eligible to take the upgrade exams. The upgrade exams and the 40% savings offer are both intended to recognize your investment/expertise on our current technology and help your transition to the new stuff. So you should take advantage of it.
SO SIGN UP FOR YOUR VOUCHER. NOW! <super pushy sounding> ALSO, TELL OTHER MCSA/E 2003s BECAUSE YOU CAN ONLY REGISTER UNTIL THE END OF JUNE. <she says, as pushily as possible>
