It turns out because of the update, there is an even simpler way to see if you're enrolled in the bungie beta testing program. On your profile page on the header, in the bottom left there is either a link or this icon - depending on your status if you're enrolled.
If you want to take part in their beta testing, make sure it says you're a test subject after [url=http://www.bungie.net/en-us/Questionnaire/UserResearch]completing the survey.[/url]
PS: The drop down menu top right has also been changed to "User Research" instead of "Beta Test Our Games".
