That was a really funny afternoon when I started that project. However, don't get me wrong, I included anything kissing or better, including Raisin Weekend forfeit and truth or dare kissing, which put a lot of peopel into that map who wouldn't otherwise be there. And then, because some people like Oli have been around for ages, we were able to tie other people in, back through, and in again.
I was recording things that happened that I'm not supposed to know about but have since lost the paper. Someone may have major blackmail potential.
