Code that you insert on this page could contain malicious content capable of compromising your account. If you import a script from another page with "importScript", "mw.loader.load", "iusc", or "lusc", take note that this causes you to dynamically load a remote script, which could be changed by others.

A guide to help you find broken scripts is available. If you are unsure whether code you are adding to this page is safe, you can ask at the appropriate village pump.

//Shamelessly stolen from [[User:Ais523/highlightmyname2.js]] and modified for my use.
//This script highlights all instances of the logged-in user's username on pages by
//giving them a gold background. It only checks bodyContent, not titles or sidebars,
//and doesn't change edit windows or Special:Preferences.

/* You can highlight a string other than your username by writing
 * hmn2username="stringtohighlight";
 * just after the line and/or lines that you used to install this script.
