I'm seriously considering switching my current domain name registrar, PlanetDomain, due to thei erratic service.
Does anybody have any experience in moving current domain name users to another registrar? Is it possible?
People do it all the time. Just initiate the transfer from the new registrar that you want to move your domains to. Ensure that your domains aren't locked at Planetdomain before you do though. You also want to ensure that your e-mail is on record for the whois lookup.
