I hear about them more on the pre-allo forum. Here's a good quote:
" Assuming you are just now applying for 2009 matriculation, most write the
Letter of Interest after the interview. Often it is combined with what you'd put in an update letter, but mainly you would write what you like about the school, and why it is a perfect fit for you. Perhaps you'd add that you look forward to receiving a letter of acceptance from them. This type of letter can be sent to multiple schools.
A
Letter of Intent would only be sent to your top choice, essentially promising that if you are accepted, you will drop out of consideration by all other schools and promise to attend that institution. It is a written contract, so don't send it unless you are seriously sure you will carry through on your promise. Would it be enforced if you change your mind? Probably not. It is an honor thing and would effect the way you (and others) think about yourself if you break your word."
I'm still trying to figure out if the latter is a good idea. I don't mind if the school tosses it out, but I don't want it to hurt my chances. Either way I'm going to wait a couple of weeks to draft it perfectly. I've been in communication with the admissions office, as I've said, and based on the amount of mail they claim to be getting, I won't be looked at for a while. My DO letter writer also wants to call and make sure they got his form. He claims that a call from his recommender is what got him an interview at CCOM back in the day.. hehe..
