What are the cons of setting up a Facebook Group for my son's elementary School?

[Foulish121]

The downside to Facebook is what makes it great - everyone can see it (Unless you specifically set up the account or group to restrict who can or cannot see it).

I would say that the downside to a group on Facebook for a school of young children (I'm not up to date on the American schooling system, so I assume elementary is the title given to young children) is that people who do access it might be using it for other purposes - in short, don't post anything of a sensitive nature - especially when children are involved.

You may want to set up a system in your school where the parents have to submit their name and you send them the invite or friend request.
