i have a co.cc domain before. it is stated that renewal is free for personal use. but i have a doamin i used previously that requires $3 for renewal. is this correct?
According to www.co.cc, yes it's free for personal use. If you are being billed then you should contact support at co.cc. You may need to prove the domain is for personal use only - if you have ads on there, you won't have a good case.
Domains are only a few bucks a year, why not shell out for one?
