As Chris Tulach may have mentioned on the RPGA boards this is an international program (rewards in English only though). Here is the official FAQ:
Q. Where can I find out about DM Rewards?
A. Head to
www.wizards.com/rpga/rewards This page outlines the program’s benefits and the specifics for earning rewards, and provides you with a link to sign up if you’re not already a member of the DM Rewards program.
Q. Do I have to have a DCI or RPGA number to sign up for DM Rewards?
A. Yes. You can obtain a number by attending an organized play event, such as a Living Forgotten Realms game or Delve Night. Alternatively, you can go to our Knowledge Base at
http://wizards.custhelp.com and you can search our help for information on getting a number.
Q. I just signed up for DM Rewards. Will I get the adventure that was recently sent out?
A. Yes. We will continue to send the DM Rewards adventure for 2009 (“The Village of Hommlet”) to all new participants in the program on our mailing schedule. Our next mailing is scheduled for August, and we have mailings planned for October and February 2010 as well for those that sign up in 2009. So, if you sign up now, you’ll get the 2009 adventure in August. If you sign up in summer, you’ll get the adventure in October; those signing up in fall will get the adventure in February 2010.
Q. I live outside the US. Will I get DM Rewards?
A. Yes, as long as your contact information is valid, you should receive the DM Rewards that are due to you, no matter where you live in the world.
Q. Some people say they are receiving their rewards, but I don’t have mine yet. What should I do?
A. Wait until the month following the mail-out month. If you still haven’t received your rewards by then, you can contact us through our help system known as Knowledge Base at
http://wizards.custhelp.com.
Q. Do I need to update my contact information to continue to receive the annual contact mailing for 2010 and beyond?
A. Yes. In your sign up year, you don’t need to update anything, but in order to receive the contact mailing for 2010, you’ll need to log into your profile and confirm your contact information by March 31, 2010. Even if you don’t have any changes to make, you’ll want to verify the information we have is correct and update it. In this way, we know you’ve logged in and verified your contact information. Simply log into your profile, click on “Personal Info,” and enter your information.
Q. I noticed by reading the DM Rewards information that I get cool rewards just for DMing games. Do I earn any points for playing games?
A. The DM Rewards program is meant to reward DMs for their hard work and time spent running D&D games. Playing a game does not earn you credit as a DM.
