# Who is the "Challenge Master?"

Who is the "Challenge Master?" I've been wondering if it was just a bot but it doesn't seem to be so. Who is it?

Nihar, which topic is given to you to moderate ?

There were originally three challenge masters : Calvin Lin and Arron Kau for mathematics and David Mattingly for physics.

Not sure if it's changed now or not. Haven't seen David post anything since quite a while, so I think he might have left Brilliant and new challenge masters might have been added in. Arron is still active but not as much as Calvin. You might as well just say that Calvin is the Challenge Master for mathematics since he's almost the only staff member who's almost always active on the site.
