Welcome to WebmasterWorld!
Please read the forum charter [webmasterworld.com]. WW does not permit recommendations of registrars, as it is open to abuse. If you want to protect your domain, you should seek a registrar that allows for domain locking. That will prevent unauthorized registrant and name server changes, as well as malicious domain transfers. For maximum protection, select a username / password for your account using a combination of at least 8 characters of uppercase / lowercase letters and numbers. You should also be alert to attempts to steal your login info via phishing.
