[@Loki Odinson]Other school students would be fine to go on the trip; however a bulk amount of the story will actually take place back at Hogwarts.  That said Iam sure we can come up with a good reason for exchange students. 

Personally I am wanting this role play to, for the most part, be removed from the books by way of the great war and whatnot. I am not saying we can erase them completely, but maybe this happens after Harry's and the gangs kids graduate so we don't really have to worry about stepping on those toes. 

I know it is rather bold of me to expect a role play to go beyond the first main act, but there are a few story lines I would really like to explore.
