Relax!
I am sure this is stressful, but you got back to them right away. I doubt that Fulbright would penalize you for someone else's mistake. Additionally, what I think this points out is just how far behind the State Department is since they said they would notify us of missing transcripts quickly after the February deadline. Just relax, you did what they asked and now you need to go on with your life as normal (except maybe just prepare for an even more prolonged wait).
Mozartgirl53, I think you'll get if and if you don't it will be Fulbright's loss, not yours. If worse comes to worse, there are other funding opportunities. I believe in both your project and your passion and I am sure most of the other people on this forum do as well. If I had the money, I'd probably create a fellowship just for your project (and Oliowoo's).
