<p>Okay I have the answer to this problem. I was accepted to the University of Delaware. I did receive a phone call on Tuesday. The call said as follows: my name, that I have good news coming in my mail box next week, and that they would like to invite me to the Destination Delaware event April 13th-15th. This means that I was accepted, as my friend called UD the next day, and they said that they called accepted students who applied with an ethnicity. I am half-Hispanic which I put on my application, therefore I was called. They reassured her that the letters are supposed to come next week in the mail. I have pretty good stats on top of the fact of my Hispanic heritage. They would not invite people who have not been accepted to an event well after the decisions are mailed out, and the University of Delaware admissions office confirmed it themselves. If you look on twitter, a lot of people have been getting accepted too. So there should be no worries, if you did not receive a phone call and did not apply with a certain ethnicity they were focusing on (I will assume Hispanic or African-American) then you are still in the running 
I also talked to admissions on the chat last week and they said they were hoping to send letters out on the 15th.</p>
