How funny that they first told you they were not taking students this year! Congrats again for having a successful interview, and you are one step closer to be accepted! Sorry if you have already mentioned this in other posts, but is your field in photography and film studies?
I made a grave mistake by writing the wrong professor's name in my first email when I tried to introduce myself and my research interests, and I never heard back from her after apologizing as soon as I found it out. Although she won't be my primary advisor and I did have her correct name in my SOP, I think I have left a bad taste in her mouth, and my chance of getting into the program is even slimmer, I suppose.
