Introducing myself at AoPS, and what's your magic wand?
asuth_asuth   1170
N 14 minutes ago by jmr2010
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.

Yeah, I would advise disabling shouts on your blog until AoPS fixes this. Add the following to your CSS:

#message-box {
display: none
}

Or just switch "Show Shoutbox" to no.

It happens when someone pastes a certain html code into the shoutbox or as a blog post. This also happened to my blog, c1861700. However, it works perfectly fine when viewing from the my blogs tab.

Here is a snippet of css that will disable comments as long as people don't use inspect (also set "Show Shoutbox" to No):

.post-comment, .blog-post-comment, .cmty-posting-environ {
