Yes, you put all that stuff in there, but when you edit your personal settings, only those you want to see your full page can see it.
If someone does a search of your name, they will type in your full name and that is how they will find you. They will then have the option of sending you a message to be added as one of your friends. If you decide you don't want to add them, then they won't see your full page.
Likewise if you do a search for old friends and family.
I'm on it and I love keeping up with old friends and family I rarely see, as well as those I do see often and my daughters and nieces, etc. I don't post a lot, but once you get the hang of it and realize that cretins can't get onto your page and scope you out, you relax a bit and have fun. If you want, PM me and I will give you my full name to find me and we can be facebook friends too!
