Yes! I know what you mean! I check my mail everyday only to find it empty. I too heard that the latest they will mail decisions is on April 1st.
a friend of mine says she got a rejection letter last Friday. However, I don't know if it was a full rejection or waitlist or what not...all I know is that it definitely wasn't an acceptance.
Do you think this is potentially good news for us that we haven't heard back yet?
