Color me slightly bemused (and secretly delighted) at all of the weird subcultures that are the direct result of easy (and anonymous, if necessary) internet communication. One of Meetup's largest membership groups is, of course, Teen Vampires; their information page specifies who can join:

Meetup with other Vamps, ages 16-19. There are no posers or role players allowed. THIS IS FOR REAL TEEN VAMPIRES.

Fantastic. And a useful introduction to this group, which, to me, provokes the same intoxicating mixture of glee and dread.
