WOOT early bird pricing is in effect, don’t miss out! If you took MathWOOT Level 2 last year, no worries, it is all new problems this year! Our Worldwide Online Olympiad Training program is for high school level competitors. AoPS designed these courses to help our top students get the deep focus they need to succeed in their specific competition goals. Check out the details at this link for all our WOOT programs in math, computer science, chemistry, and physics.

Looking for summer camps in math and language arts? Be sure to check out the video-based summer camps offered at the Virtual Campus that are 2- to 4-weeks in duration. There are middle and high school competition math camps as well as Math Beasts camps that review key topics coupled with fun explorations covering areas such as graph theory (Math Beasts Camp 6), cryptography (Math Beasts Camp 7-8), and topology (Math Beasts Camp 8-9)!

Introducing myself at AoPS, and what's your magic wand?
asuth_asuth   431
N 12 minutes ago by Ultimate_Frisbee
Hi!

I'm Andrew Sutherland. I'm the new Chief Product Officer at AoPS. As you may have read, Richard is retiring and Ben Kornell and I are working together to lead the company now. I'm leading all the software and digital stuff at AoPS. I just wanted to say hello and introduce myself! I'm really excited to be part of the special community that is AoPS.

Previously, I founded Quizlet as a 15-year-old high school student. I did Course 6 at MIT and then left to lead Quizlet full-time for a total of 14 years. I took a few years off and now I'm doing AoPS! I wrote more about all that on my blog: https://asuth.com/im-joining-aops

I have a question for all of you. If you could wave a magic wand, and change anything about AoPS, what would it be? All suggestions welcome! Thank you.

AoPS Wiki signs out
k1glaucus   15
N Today at 4:47 AM by Yiyj1
Summary of the problem: Whenever I go to AoPS wiki, it signs me out
Page URL: https://artofproblemsolving.com/wiki/index.php?title=Main_Page
Steps to reproduce:
1. Go to AoPS wiki
2. In the top right where normally it would show your profile, it shows the sign in button
3. Pressing the sign in button also does not do anything for me, it just refreshes the page
4. If I go to any page I can't edit it, so it's not just a display bug
Expected behavior: I stay signed in
Frequency: Every time
Operating system(s): macOS Sonoma
Browser(s), including version: Safari
Additional information: Clicking sign in doesn't work, it just refrfeshes the page, and if I go to any other page I'm signed in again.
