I have one because I "friended" a niece who asked me to join.
I'm not any too sure about it now because suddenly strangers keep popping up. Finally discovered that one man was an Illinois
Step-GD's boy friend. Another lady showed up, she was a letter writer from another forum and I'd never met her, but it gave her name and picture. I'm not at all happy about all these people having access to my email address book, and don't quite know how to get out of it. I'll have to ask my son or one of the teens in the family~~
