We hope everyone's been enjoying their winter break because it's about to get better!

In the coming week we will be hosting two contests: the Mackenzie New Year's Challenge, and DMOJ's own New Year's 2016 contest. Please see the contest pages for details.

Anyone with a DMOJ account is welcome to participate, and anyone without one is welcome to register and participate.

See you soon, good luck, and Happy Holidays from all of the DMOJ crew!
