The letter just tells you to go to this website:

All of the instructions for accepting/declining an award are there. I believe that all you have to do is email someone. Hope that helps.
I am also in psych at Queen's. As of 30 minutes ago the psych department hadn't heard anything. Dianne Flint said she would email the second she found out. Hoping for news by the end of today!
