Hi I had a URL (www.abc.mx)(example) with a diferent provider and the applicationcode is hosted with you with the domain name (example) abc.mx, right now, the url is experied, I dont need that url anymore, also I dont need the code. However, now I have a new URL with a complete diferent name (www.zzz.mx) and will be used for other things (new code)... so my question is, Do I need to cancel my current Domain Name and hire a new one, or Do I need to change the Domain Name? Let me know your comments...
