Facebook and Myspace are great. This one poster said write a letter. With email, facebook and myspace, you will save on stamps, especially when you are sending pictures with a regular letter and you could probably only send 1 or 2 pictures to stay within the 1 oz limit.
With e-mail, facebook or myspace you don't have to worry about sending pictures through the mail. With e-mail there is a chance of getting a virus through the pictures but with myspace or even facebook, your child can look at the pictures and comment on them.
The majority of my nieces and nephew who are under 18 have an account on mostly myspace. I get to check up on them ask them how they are doing in school. Since I can not go to their games, pictures are posted on their page. On both accounts you can allow only people who you want to add as your friends.
Since your child has your email address, everytime your child gets a message on their facebook page you will get an email and on that email it will say what is on facebook. If you don't want your child to see the message you can always go on their and delete. The same with myspace, you can always delete the comments or even the inbox.
Remember when the child do their profiles, less is more, when it asks for the city and state . Anywhere, CA or whatever state you are in. When it ask for a school. You can say Anywhere Middle School. You just have to be careful what your profile says.
GO FOR IT, and if it is a problem, you can delete the account.
But be forwarn all you parents out there. I went to the library to take a test and there was this 9 year old and this 12 year old using the computers and they both were up on myspace making a profile. These kids are smart, they know how to get an email address and they know how to make their own profile page. So if you don't let them have one so you can monitor it, they can go behind your back and do it themselves.
