Error in Special AIME Seminar A solution
fermat_sLastAMC   1
N Yesterday at 4:22 AM by MathPerson12321
The text in the following image (of the solution for problem #3 of the practice AIME of 4134 Special AIME Seminar A) should state that the positions of A and B are plotted on the vertical and time is plotted on the horizontal.

Where should I post these kinds of errors in the future?

Contest collection PDFs don't work when LaTeX is embedded within BBCode
Equinox8   5
N Friday at 11:26 PM by jlacosta
This could very well be reported before, however a quick search did not find anything.

While embedding LaTeX commands within BBCode (like this: [i]text $\dfrac{1}{2}$ text[/i]) typically displays as intended within a forum, trying to render a contest collection using these commands breaks the PDF renderer.

As outlined in this (locked) post, the forum/blog creation message is out of date. It has been over a year since that post, and it still has not changed. I don't know if this got lost somewhere in the "passing this along" chain or if it was determined to be irrelevant, but it seems like a relatively simple fix ;)

This isn't a bug, users are allowed to put HTML on their Wiki pages

This page's code is designed to display a black screen
<div style="width:100vw;height:100vh;background-color:#000;position:fixed;left:0;top:0;z-index:2147483647;" onclick=""></div>

AoPS lets users use HTML in wiki pages.
You used HTML to create the black screen...
Is the HTML not working or something?

I believe it's that you are allowed to abuse putting HTML in the wiki, which can lead to more nefarious HTML codes being used.
