/* timeless-newMessageHighlight A script to highlight the username in yellow when there are new messages on your user talk page (since the in Timeless skin, the talk page link is hidden in a dropdown). This script should only be used with the Timeless skin -- add it to your timeless.js, not your common.js! For details on why this is not done by the skin, nor by the Echo extension, see these tasks: https://phabricator.wikimedia.org/T215695 and https://phabricator.wikimedia.org/T216046 // Wait for page load $( function($) {
