Academic year in America (AYA) anybody know?

Hi, I have recently come across this programme http://www.academicyear.org/ It seems absolutely perfect for me, as I don't know what yet to do in college here in the UK (you get it free if you enrol before you're 19) so I thought it would be a good years break. If any people have read my previous questions I'm sure you'll know I have a deep interest for America. They say you exchange your culture with an American family, although I may be British we still have a different culture. I only say this because when it says contact your local office, I am unable to as they do not have an office in England, I have sent three e-mails, one to the American base, to a French speaking office, and to the one in Germany all 3 in their native language. I have not yet received a reply from one and these where sent a lot earlier in the month. Just wondering if anybody from the UK has done this or would know if I can do this? Thanks a lot :)
