I would like main domain like www.site.com to be store of business. I would like to have a subdomain like employees.site.com that will be start page for Google services. Is this possible? Any questions just ask. Thanks for your help.
I would maybe still like to keep Google Sites as maybe an employee only site that can be accessed from a subdomain such as sites.site.com
How do I change from Google Sites to Godaddy or Hostgator for hosting?
