Once you create your website, the domain name can not be changed.
What are my options?
1. You can register a new website under the new website address. In a Webnode account, you can create more than one website.
2. If you want to change the name of your website, you can register your own domain (myweb.com) for your website. You can do it directly in the administration of your website in the section "Register new domain". The address will be for example www.myweb.com (without "webnode" in the address).
If you register a new domain name in Webnode, we will take care of all technical aspects and your project will be available under the new domain. The registration process is completely automatic, so you don't have to do any configuration, our system takes care of it. In fact, you can continue editing your page as always. Check the article Domain registration for more information.
