How soon after getting the call did you guys receive your admissions packet in the mail?
Mine was mailed out the day after I received the acceptance call, and arrived almost a week later. It's sent via USPS snail mail, so your receipt will depend on your proximity to SoCal. If you're in the general area, you'll get it in a day or two, if you're a long way off, like I am, you're probably looking at a week.
Just a heads-up, there's not much in the admissions "packet." There's a one-page acceptance letter, a short scholarship/fellowship letter (if you receive any), and a scholarship/fellowship questionnaire (again, if you receive any). They don't send any goodies, further program information, link to admitted student portals, etc.
