Yeah I was team mom for my sons football team for a few seasons way to many phone calls.
One thing you could try is ---collect all of their emails and put them in a "group" in your email address book and mass email updates
(with the smart phones most people have emails going to their phones)
I have two children over 18- and I have been telling them watch what you post on facebook including pictures Because Today employers look at it for background checks........so what seemed like "fun" in college could cost you later in life but they just dont get it , seem to believe those things never happen to them. Sometimes all you can do is inform and pray for the best (((((Hugs))))
