I share in your disappointment. I also looked into the auxiliary program, but after reading countless blogs, I did not think it was worth it to go through the application. I hope you find something! If it's meant to be, it will be. I suppose that this year just was not our time.
I'm a psychology major with minors in Spanish and photography. There are certain things that happened AFTER the deadline that could have strengthened my app (maybe). I proposed to do an after school photography club that would require the students to go out into the community and document life in Spain. We'd then discuss photos together each week. It's pretty simple. What did you propose? I saw a vid once with one of the Fulbright people from Spain. She said that they don't care what you propose (as long as it's feasible) - they just want to see that you're proposing to spend your time doing something outside the classroom.
Best of luck to all of us! I'd just like to stop shrugging my shoulders when people ask me what I'll do after graduation. It's time to have a real answer.
