Anyone used the Family Room or Groups on your WP?

I recently broke down and got my kids phones. They swore to me how tortured they were being the only teen-agers in the world to not have smartphones. Actually, what did it was the fact that they are in different schools now and have to catch buses and various rides to get to their activities. I wanted to be sure they could contact us any time.

So, I got them Lumia 920s and used one of their new phone discounts to upgrade to a 1020 :) While I was setting them up, I noticed the Family Room - something I have always ignored until now. So, you get a private chat room, photo page, One Notes, and a Family shared calendar everyone can see.

Maybe I missed it, but this is the stuff MS needs to be marketing the heck out of.
