Guys, try to calm down and focus on other things today. Last year, invites and outcomes from Wharton came in at random times, but almost all arrived after noon - 1:20pm, 5pm, at one point even later. No need to refresh, and please, try to keep comments relevant and useful. I am anxious too, but reading about anxiousness when you are anxious doesn't help.
In fact, I propose for everyone who wants to chat about Wharton and the interviews today, go to the GMATClub chat and join everyone else who is anxious:
