Congratulations, Steve. Just saw the results hit the BJCP database. It's the most difficult rank in the BJCP to achieve, and well worth celebrating. I don't think anyone who hasn't taken the exam can really understand how hard it is to do what you just did, so let me provide a little perspective:
Of 5829 judges in the BJCP, only 91 have reached Master. Good on you.
Since you won't need to be studying any more, maybe you can help grade some more exams...

Next stop: GM I.
