FB accounts are OK - once the novelty wears off, the privacy issues settle down, and those pesky restraining orders are lifted...
In honesty, I was very grateful to have access to so many people who were involved in my mother's life after I went off on my own in '90. I went off on my way, and tended to not look back - and I've discovered that I missed a neat person. She made life better for a lot of people, and I never would have known that were it not for access to those people via FB.
I've been able to reconnect with old friends, make a few new ones, all without drama. There can be actual adults on FB.
