I called the NSF GFRP office today to ask about what was going on. They told me they still have no new information and will update the website when they do have more. The lady on the phone was able to tell me that the for those who are funded, the funding starts on June 1st so I guess we could consider that the absolute last day we could find out. Which is unfortunate because my advisor told me yesterday he can't pay for me this summer and I have to decide on whether to try to join another group for this summer or sit on my ass and just hope the NSF solves all my problems.
