I wasn't very clear I'm afraid.
What I want to do with my Hosting 2 plan is create one main account and create a bunch of subdomains under it, each representing a branch of my business. I want to register various domain names which might be typed in by people looking for my services, and direct them to the appropriate sub-business. I don't want to mask where they end up, I want the linkage/branding exposed.
For example, I have brucecannon.org and want to use it as a portal for my various business endeavors. I've also registered donationbox.org and I'd like to forward it to interactivegiving.brucecannon.org, a site which will offer custom interactive donation boxes for galleries and museums. And so on for all my various little businesses.
So I think I just specify PZ's name servers at my registrar to bring people to brucecannon.org, the main account I've set up, and that the linkage to my actual folder is made through the name.
And I understand how to create subdomains in either of the control panels.
I don't understand though how to specify a subdomain address, either at my registrar or at PZ.
I reviewed your suggestion of "parking or pointing a domain" in WHM, but this appears to be designed to mask the actual source of the page. This would be much better than nothing but what I ideally want is unmasked forwarding to a subdomain.
Sorry if this is still pretty muddled, I've got a lot to learn yet!
Thanks for your advice,
