My application arrived in HLS last Nov 30 (or so the FedEx website says)...does anyone here already received any email confirming receipt?

I received one. Without confirmation that they received all the documents.

if you dont mind me asking, how many days elapsed from the time they received your application to the time you received the email from HLS? thanks.

I sent my application on November 20, and I received confirmation on November 25. But I guess that if you sent your application shortly before December 1 it may take longer to confirm.

My application was received by Harvard on 1st December via FedEx. I received the conformation e-mail today from Harvard which is pretty quick considering there was a weekend in between.

oh no. FedEx delivered my application Nov 30 and I still havent received any email from HLS. *gulp*

I wouldn't worry about it too much. They probably got a ton of mail and are still sorting through it. If your application is post-marked and some kind of marked from your courier as December 1, they will accept it.
