Kathy,
I am not totally sure either, I think it is sorta like Facebook and other sites where you have a list of users who you frequently visit or chat with. It does not exclude anyone else just list those who are special to you.

Neva, I got your request the other day to "Friend" me and was touched and flattered, but also unsure exactly what that means. I'm kind of old and don't always know the etiquette for this on-line stuff. I couldn't find anything that explained it. What is the response I should be making. I found this message box totally by accident. - Kathy LeDonne
