Testing demo " BuddyPress Themes In Action"

Greetings

I have a WPMU Premium account

I want to create a website similar to UMWBlogs.org

I was hoping to customize a theme to look like UMWBlogs.org and wanted to

call marinprofessionals.com

Marinprofessionals.com is currently being hosted by Godaddy

hte server names are bellow

nserver: ns25.domaincontrol.com 216.69.185.13

nserver: ns26.domaincontrol.com 208.109.255.13

I paid for IncSub to have the installation done but apparently

it only installs to their own servers(bellow):

Please set the nameservers of this domain to:

ns11.psekhosting.com

ns12.psekhosting.com

So I used filezila to upload bbpress and WPMU to Do daddy account and

was hoping I could godaddy servers instead of pSek servers

it is possible, if if so, is there any documentation I can use to accomplish that?
