New
$vbulletin->options['usepopups'] = 1;

Don't know why this would not take effect from the front-end. Oh well.

This is going to be a problem for people who can't use popups, such as in javascript is off or maybe mobile browsers... you should double check your site using firefox with the script-block add-on (or turning off js in any browser) and seeing if you can still get basic functionality.
