no one know why it does this but the facebook team! so what you have to do is set up a new account
imvu will always let u sign up sumone might hav ur username
As long as you have different e-mail addresses it's not a problem. Just sign up for facebook seperately. Then you have the option to "marry eachother" on facebook. You can do the same with other family members also. rubiconn.com
Well Facebook won't let you sign up till you are 13 so yer 13 is probaly best!!
to do this just type facebook in the google bar at the top and then a result should say facebook login.Also it will say sign up and if you want to have a facebook just click SIGN UP.
At the moment it doesn't cost anything to sign up for facebook.
cheese puffs are too awesome
You can, everybody can sign up on Facebook. just visit www.facebook.com and sign up.
What?
A Facebook account is no longer required to sign in on Answers.com.
You are not allowed to use Facebook without the sign up procedure. You can access limited Facebook pages without going through the sign up procedure.
i am pretty sure it just does that because of the birth year that you put in. if you are under 18 it will not let you sign up. so if you really want a facebook, you should just lie about your age. that is what my younger cousin did.
