UsernameAvailability allows a user to quickly check the availability of an inputted username. The script inserts a "Find a username" item to the user's "My Tools" menu, which, when clicked, opens a modal with an input textbox.
Queried names are displayed in the modal log as links to the associated user pages, and if the account possesses a registration date, it is displayed in parentheses after the entry.
For security's sake, input is limited to 30 characters and special characters are forbidden.
Effects of this script can be seen in the toolbar of this page.
