You can easily use your own domain name with your XSYTE.

There are two basic ways to do this.

The first way is to simply point your domain nameservers to
NS1.XSYTE.COM  
NS2.XSYTE.COM

The second way is useful if you already have hosting and wish to continue using email services.

Edit your DNS Zone
Find the 'yourdomain.com' or '@' A record and change the IP address to 66.84.15.31
