As of August 19th, 2008, only 31 people in the world have passed the MCTS: MDOP test.

According to the official statistics on Microsoft's site, 31 people have passed 70-656: Microsoft Desktop Optimization Pack: Configuration.

Which means, there are still 169 MDOP Charter Memberships up for grabs.

If you are one of the first 200, you get:

#1: MDOP Charter Member jacket (ooh!)
#2: MDOP Charter Member Glass Award (ahh!)

If you are lucky, the promotional code of "MDOP" is still valid and you can take the exam for free, like I did.

Other statistics that I found interesting because I have these newer certifications (worldwide numbers!):
