We actually wanted to continue the trend of posting photos of contest writers, but we could only find one photo containing both of us, which was a group photo that we took with some other UK informatics people! (I'm the one in the back of the picture who is wearing the MHC T-shirt and [user:yud08,2024-10-23] is the one whose head is popping out from the left side of the photo.)↵
