The message I got from the program goes:
"GSAS issues the decisions. You should be notified by mail no later than the end of March or early April. "
So, good luck to all~!
I would vote for postal service. The website one is really weird. What website could it be except for applyyourself? This is not a very big program. I don't think they would reveal some results and hold on to others, would they? We'd better just wait.
