Because something awesome happened at the Pumpkin Post today. It involved Vampyres and gameplay videos.
You should read the Pumpkin Post more often.
Update: I've just been emailed with a "Hey I need to join to watch this". This seems to be the case...except that, for some reason, I was able to watch the video without joining the first time. Anyone have any idea on what's going on? Can anyone post the video on YouTube, too?
