× This is an error feedback message. It may have links included in it, some of which may have been visited already, and which the user may hover over. It is also common for feedback messages to include a list:

• Please do this one thing.
• Oh, hey, and do this other thing also.
• And when you're done with that, take a nap.

Feedback messages may ocasionally have additional text, and sometimes even blockquotes.
