This is probably a dumb question, but I'll ask anyway.
I'm submitting my application along with the neccesary essay which outlines my career history and future goals. I'm wondering how to address the letter in an online application. Did you put an actual header on it with school name, address, etc. Also, did you simply put: "Attn: Admissions Committee", or something more personal?
Errr... I do not quite understand, what letter do you mean, usually online application does not require any additional letters to be sent.
