After Mathcounts
Existing_Human1 10
Hello Community!
I am officially done with my mathcounts career, as I have officially failed state, and I am now left an aloof blob reminiscing about the good old days.
So ... I was wondering if any of you have fun competitions I can do to relive the glory days of mathcounts. Obviously, their are the AMCs but I'm looking for something more team/travel based and one that preferably has a CDR.
Please specify if the competition is team based and if it has a cdr, and also when it takes place
Thank you in advance!

Differentiation Marathon!

Hello, everybody!
This is a differentiation marathon. It is just like an ordinary marathon, where you can post problems and provide solutions to the problem posted by the previous user. You can only post differentiation problems (not including integration and differential equations) and please don't make it too hard!
Have fun!
(Sorry about the bad english)

Introducing myself at AoPS, and what's your magic wand?
asuth_asuth 565
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.

You have used a banned term. Please edit and resubmit.

I have been writing a blog post and it says there is a banned term. I checked it over and nothing seems to be wrong, there is no foul language or anything. Why does it show this and am I able to access the list of banned AoPS words so I can submit the post on my blog?
