You should have received an access PIN via email and/or text.  If not, call us at 310-310-3590. Once admitted, click the full screen button (bracket icon) on the top menu or press "s" on your keyboard to expand your video (menus appear at the top and left when you move your mose). Your mic is muted so if you need to talk (you'll want to think really hard about his one), hold the spacebar to unmute your mic.  When you release the spacebar, your mic will be muted again.  Have fun!
