Two related bugs:

1.

• Go to the Recover Password page.
• Enter an invalid username/email (e.g. one that contains spaces).
• Press submit button.

The form returns the "Incorrect input" error.

2.

• Go to the Create An Account page.
• Enter an invalid username (e.g. one that contains spaces).
• Press submit button.

The form returns the "Invalid input." error.

/me leaves mid-ticket, I'll improve this description later.

If you click on the expanded drop-down list, it will disappear. If you click on the original button, it doesn't disappear. Both of these behaviors are wrong.

The expanded drop-down list should disappear when the user clicks anywhere but on the list itself.

(Also, it needs some small styling changes to make it look like the button and the list are visually connected.)

On the "Changing account settings" page, there is a form to change your password. This is mixed in with other, less invasive, account options such as comment notifications.

I think they should be separated and the page should have a link saying "Change account password", which links to a new page containing the form to change your password.
