From the GC admission results page, it looks like offers are already out for Minnesota, UC Davis and Maryland for the applied/ag econ. I have particular interest in these programs because i have also applied to them. I know the posts for Minnesota are legit because I have also heard back from Minnesota with an admission offer but no funding. As for the posts for Davis and Maryland, it was just one post so don't know if those are legit. Don't lose hope ... since they didn't write back, it looks like you are still in the game.
