Well u have Myspace,Twitter and Facebook.
Kidzworld is one.
bebo
No, Habbo is not good for kids under 13 because there is some offensive language in there.
First off, 13 years old is a pretty mature age. (Depending on who you are.) Most 13 year old will not be satisfied with PBS kids, etc, etc. Some good sites include: www.stardoll.com (for those girls who like makeup and celebrities) www.nexon.net (some of these games may be a little inappropriate)
there is Clubpenguin, fantage mushimonsters, and stardoll!those sites are for kids 7- 12.
Meez Isnt For Under 13, Its For OVER 13.
moshi!cbbc!and gogirlgames!
www.kidswirl.com is the best website and www.facebookforkids.com kidswirl is good because parents can watch what the kids r talkin about
you need to be 13 but gaiaonline.com is the best for seventh graders
not good, against some sort of privacy law
A website that I would recommend would be Buzzle.com i enjoy that one! Try it!
Here is a list! Clubpenguin Buildabearville Fantage Stardoll Whyville Dizzywood Panfu Quizlet Neopets Cartoon Network Disney Kidzworld Chat Avenue Betweentalk This is ALL I know I hope I helped.
