This butler lets you know when one of your distinguished colleagues has
/u/ mentioned your username (e.g. /u/reddit) in a comment anywhere (that you can see) on reddit. You'll get an orangered, and the comment they mentioned you in will appear in your inbox. Use this information wisely for maximum comedic effect.
If you'd rather your ears burn unexplained, you may turn off this feature in your preferences.
Note: the butler won't notify you when you mention your own name or when the mention is in your inbox already. That'd just be silly.
