There are several reasons why you might not have been able to start an account. When you sign up, make sure you start here:

http://www.xanga.com/register.aspx

After you choose your username, password and submit your e-mail, you'll also find two small boxes - one to make sure you're over 13, and the other to agree with the Terms of Use for Xanga. Make sure you fit those requirements and agree to the Terms of Use. Select them, and then Create Account.

It is possible to be rejected if another user has the name that you want. If that’s the case, just choose a different name and try again.

Once you found a unique name that nobody else has on Xanga, then you're on your way! Follow the easy steps to set up your site, and your site should be up in minutes!

If you're still having trouble - make sure your password matches up. If your password differs from the other one, then you would not be able to join.
