My site offers free webhosting accounts (as well as paid, but my question for application applies to the free accounts), and a client without a domain name may choose to use a subdomain of any of three different domains, none of which are the domain to which WHMCS is to be installed on. Is this possible with WHMCS? For example, the domains will be as below: domain1.com = WHMCS installed domain domain2.com = 1st domain choice for sub-domain accounts domain3.com = 2nd domain choice for sub-domain accounts domain4.com = 3rd domain choice for sub-domain accounts Is this possible with WHMCS? Thanks, Frail
