Couldn't find a 2003 or MCSE forum so I hope you don't mind me posting here?

I am an MCSE but only in Windows NT. I have a chance to upgrade that to 2000 or 2003 and I am considering going for the latter whilst taking as many of the exams (with self-study) as I am able. My main question is that on the NT MCSE track you had to do all your exams within 12 months, is that true of subsequent MCSE's?

Thanks for any info :-)
