My daughter (nearly age 13) has been sent invites from one of her friends (age nearly 12) from both sites. I know very little about them, but hubby definately isn't convinced by her having an account with either. Does anyone on here use it and can tell me more? For example can you limit it to only people you know? Is there anything to watch out for? Tried looking around Bebo abit but found it confusing without having my own account - seemed to be a lot of people who were in their late teens/twentys. She has been quite grown up about it, in that she hasn't automatically clicked on the email link but instead asked us whether she can.
