The halls of the castle have flooded with letters, and to avoid dealing with Filch's crankiness and threats to lock us all in chains some of the students have volunteered to help clean them up! So grab a bucket or a trash bin and a broom or a rake and get to work! Whatever letters you scoop up, you keep.
And if anyone finds a love letter addressed to Professor Longbottom... Can I have that back please?
Don't forget the main thread for when the event is over either!
