I always love hearing from Jonathon Rosenthal, the head organizer of The Group That Shall Not Be Named.
His Harry Potter group went to Infinitus 2010 in Orlando a couple of weeks ago, and he was kind enough to tag a set of cosplay photos on Flickr.
What a great guy — and what awesome costumes! This looks like SO MUCH fun!
