Or a website where they post stuff like that? Like the schools website? My son's school has it's own app where they post updates, photos, etc. Not a huge fan of another app, but at least it's not public and I'm not forced to use Facebook or Twitter.

Yeah, actually, that would be a pretty high bar. It puts the onus on them to maintain the list of people, to use an app that individually sends the message to everyone so you're not giving everyone each other's phone numbers.

I'd love to see them post it literally anywhere else but it is what it is.
