As Walton GOP stated, it should be fairly easy to get a list of email addresses from concerned parents, so that you could share ideas and thoughts regarding school stuff. As for the privacy issues, I'm fully aware of them, but you can have an opt-in list, so that only people who want to be on the shared list would be on the list. Anyone abusing the email system could be kicked in the booty by the other participants, kind of like SoWal.com/bb. The schools could even have a website and include a message board. Both students and parents could log in and participate.
