Thanks for the welcome!
I'll look into these possibilities!
BTW, I know we won't really integrate into Swiss society, from what I have learned from everyone that's no small task...

My older children are just happy to know kids at school that live nearby, having some experience with attending schools at a real distance from our community in MA.
This does put my 13 year old in a challenging position, being the only child in 8eme who isn't quite fluent in French, and wanting to have friends he can actually talk to! If anyone out there has an outdoorsy 13-15 year old English speaking boy into mountain biking, rock climbing or snowboarding please give a holler!
"Integration" will presumably be easier for my younger children, who are 10, 7 and 4.
We all are really active and do lots of outdoor sports. Looking forward to meeting more folks!
