Several domain names on one site
Portfoliobox can only purchase and configure one domain name for each pro account.
If you wish to get a second domain name, you can register one yourself and redirect it to your portfoliobox website domain.
NB! It's NOT the same setting as you do when you want to
use your own domain name with your pro account.
Contact your domain host and ask them how you can redirect your domain name to a specific website.
