Could this be included in the main function, it's a trivial edit and retains backwards compatibility. </div><div class="gmail_default" style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255); font-family: verdana, sans-serif;"><br class=""></div><div class="gmail_default" style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255); font-family: verdana, sans-serif;"><br class=""></div><div class="gmail_default" style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255); font-family: verdana, sans-serif;"></div></div></body></html>
