OK, I originally registered my domain at http://www.easyhosting.com, but have since changed my DNS servers myself using OpenSRS to mydomain.com's webservers. Upon renewal of the domain, who will I pay to renew the domain? Hopefully its easyhosting.com. Im confused, because mydomain.com is supposidly a free service.

If i registered my domain at easyhosting.com, do I make the yearly renewal payments to them??

It looks like all you did (apparently) was change the nameservers your domain uses to be those of mydomain.com, and that does not affect the registration of the domain, so the answer would be... you will still pay easyhosting.com for renewals.

Yes, all I did was change the nameservers...

Thanks for the assurance :) Didnt want to pay mydomain.com's high domain prices, I would rather stick with easyhosting.com :)
