Can you clarify something?
I understand that I need to choose whether to have my users utilize the A record method or the CNAME method. In the instructions there is also this note:
If your user is mapping a hostname of a domain (sometimes called a "subdomain") like http://www.example.com or blog.example.com it's sufficient to create a CNAME record pointing at their blog url (NOT IP address).
Is this method for subdomains acceptable even if I'm using the A record in general?
In other words, even if I'm using A records and IP addresses for TLDs, if a user wants to map blog.userdomain.com to username.mywordpressmultisitedomain.com, they can still just set up a CNAME like that?
