Multiple Portal Pages with Domain Names

Hello. I'm sure you probably get lots of questions about the domain names and portal pages, so I'm sorry if this is a regular.

My problem is that I can create different portal pages, but they don't have their own domain name to redirect to. I know that the portal page that is set as the default one can be accessed as the main page, but I would like to have another one to redirect to as my news page.
For an example, I have my main page as:
www.bu-gaming.com

Then my forum is:
www.bu-gaming.com/forum

For my news page, I would like to have it set as:
www.bu-gaming.com/news
But I don't know how to set a domain name for the portal page other than setting it as the default one.

Thanks for the help in advance!

Sorry no.

When you look at the portal management, you will see preview portal. That url is the url you need for another portal.

Ah, thank you for the reply.
I just needed to know how to get my other portal pages available for linking.
All solved.
