Yes, you can use your existing domain name with RunPTO. Regardless of where your domain name is currently hosted, such as GoDaddy or Namecheap.com, you will need to point it to the nameservers we provide, and we will take care of the rest of the redirecting process. We will use our service to redirect your domain name to your website hosted on the RunPTO servers. See how demopto.org points to the Demo PTO website.
