Dear fellow 365-ers,

I'm proud to announce the winner of the mundane abstract-mobilephone challenge: TODD! @olivieto is a double winner - not due to the fact that he got 15 (out of 26) votes - because he also won the mundáne-mobilephone challenge. Very special.This does not happen often. Congratulations, Todd! :)
You've got the honor to host both challenges. Good luck!
