The waitlist instruction says that any update should be submitted before 4/20/2012. For R3 WLer, how do we provide updates?

If memory serves me right, they will provide you a link to a page with a prompt for your response. I submitted an update after my Rd 1 decision, though I did not submit one in the last round.
Can anyone confirm that the Adcom has completed updating each of our profiles, whether it's an accept, WL, or ding? I have not received an e-mail with any kind of update, and I still have the WL message up on mine.
