Hi.

Check this blog at the first. We've modified our problem selection process. Now you can use this form to submit ideas. If you submitted a problem on Ninja-Setters, send it again through this form, I can't access Ninja-Setters anymore.

Still, we're in need of approximation problems, please submit them if you have any.

If you have questions, please send an email to me ([email protected]) or ask in comments. Please do not message me here.
