Microsites and Multiple Urls

Could someone please explain how this process with 4.0 works or will work?  I have seen some references during beta conversations, but I am having a hard time finding any concrete information as to the setup process.

Would I setup a page group and then use multiple url feature, that releases in Q1, to map a subdomain to the page group?

Would I buy a seperate license and just set an external link pointing to the subdomain on the page group?

Hi Stacey,

Domain page mapping feature is still not supported and we will not have the implementation in the Q1 release. There are several requests about this scenario and we are going to consider a possible implementation on the next planning.

Kind regards,
