I'm delighted to announce that registration is now open for the Fall 2013 Online Math Open! Thank you all for your patience.
For those of you that don't already know, the Online Math Open (OMO) is a team-based contest, where teams of up to four students are given over a week to solve 30 short-answer problems. The contest is completely free, and takes place over the Internet -- therefore, students may team up with anyone they like around the world.
This year's contest will take place from October 18 through October 29, 2013.
Starting this year, the contest itself will be hosted on internetolympiad.org. Team captains can register a team of up to four students there by clicking the link labeled "Register/Update Team". Note that, in particular, only the team captain needs to register on the website. For more information, please check the information page on our website.
We work extremely hard to ensure our questions are of the highest quality, so that even the easy problems will be interesting, non-routine, and not "just another contest problem". (You can see some of our previous problems, including discussion, in the contest section of AoPS .) We hope you enjoy this year's problems as well!
Best, The OMO Team
