To be honest, one of the things I was thinking about, oh- months ago, was how odd it was for a school as old as Hogwarts to be not only coeducational, but have been so for a long time. Wizards appear to have been a lot more forward-thinking than Muggles on SOME things.

But it occured to me, due to all the Durmstrang Sues, that there's really no canonical evidence to indicate that Durmstrang ISN'T a school for boys. Beauxbatons, on the other hand, I'm pretty sure is referred to as having male and female students.

Just my two cents. Bring on the homoerotica!
