alright. so i found out my roommate on the res portal and i used the 'send message' feature to send her a message. i told her to add me on facebook but either she doesn't want to...or she hasn't responded. if she responds to the message...how will i know? does it go to my email or my mcmaster email? I DONT UNDERSTAND! HELP MEEEEE!

Whatever email you put into the application should be the one you'll get the message when she replies.
