My teens have one but so do I...and I am their friend on there. I can keep up with who they accept for friends and what they post on facebook. Our main rule is only accept friends that you personally know. Dont accept friends of friends unless you have met face to face. Being military and far from home my kids and I keep intouch with aunts, uncles, cousins, grandparents, etc. Great way to see pics of family and feel like part of their world while being so far away....good luck!
I say "yes" with the caveats above. Your DD is 13 (very different from 8 or 10), and this is a learning experience that you can control and advise her if things aren't going well (cyberbullying can happen, and everyone needs to know how to deal with it). I like the idea of you setting the password (did that with mine and hotmail when they were younger). With your support, your DD will enjoy the good that can come from FB. Good luck!
I KNEW that feeding your children chocolate when they were younger just before sending them home to you would come back some day to get me. 
has had it since he was 14 - I know the password and am a friend so I can monitor what goes on. I don't go on unless something I don't agree with or like is posted and he knows it. He mostly uses it to play games!My teens have one but so do I...and I am their friend on there. I can keep up with who they accept for friends and what they post on facebook.

There are just as many kooks in real life as there are in Facebook or any other online community. My kids are too young for Facebook right now, but when they are 13 they will definately be allowed.
The most important thing in letting kids online is to teach them proper online practices, and to keep computers in common areas, like a living room, and not in the child's bedroom. It can be a learning experience for both of you, as many teenagers know much more about computers than their parents.
They said it was faster to do it for me then walk me through all the steps. Apparently, I ask too many ?'s
I say yes. But keep an eye on it... as others have said, the only way to make sure you have some control over it is to make sure you have the password, and to check out the page regularly.
Saying no to FB for a 13-year-old very often means that they create an account from a friend's computer and you don't have any way of monitoring it.
