How to install:

• If you don't have it yet, you need the GreaseMonkey extension for Firefox or TamperMonkey for Chrome. IE users have to try Trixie, and for Safari users there's GreaseKit, but I don't know if this script works in IE or Safari.
• On the github website, click on the "Raw" button above the code.
• After a browser restart you should see MathJax rendered automatically. If it doesn't work, write a message to @bass in the PSE chat.

I think if you give it a name ending in .user.js, it will be possible to automatically install it by just clicking on "Raw"

Cool, didn't know that.
