If you are hosting your website on another site and need to transfer your domain to that site, you will need to do is to get nameservers from your hosting site and point them to your domain name on Trademarkia.
Name servers are obtained from your hosting company, and are usually a few addresses that look something like ns2046.hostname.com. After you have obtained those, please do the following:
Login to www.domainmarkia.com
Click on your domain name
Select Our DNS> edit > custom DNS
From there you will see a field to enter the nameservers obtained from your hosting company. Enter the name servers there and after a period of hours, you should be able to type in your domain and it will go straight to your hosted site.
