Welcome to Lunarpages and the Lunarforums.  We can not act as the domain name register for the .co domain names, but as long as your current domain name register allows you to change the name servers you are pointing at to our name servers you should not have an issue. 

If you don't want to sign up with your main domain just yet, you could also sign up with our subdomain option which would give you something like ojunco.mylunarsite.com or something to that effect.  Then when you were ready to use your real domain name just drop an e-mail to support@lunarpages.com and we can switch that out for you.

You can use your free domain name for life at any time, and the spring offer is good till June 22nd.

Hope that helps and if there is anything else we can assist you with please let us know.
