That is what I got out of the question lol .. if he comes back and says "no I was asking for something else" then someone else might be able to help him with a 2nd option ... but it has worked for me, he asked for help and I gave it to him ...

True, he could have explained it a bit better. But with what he said you usually get what you think sounds like what that member is asking for. :P

Me myself I have 10 additional domains that redirect to my main one, a .com one. :)

ok guys.i found how to do it.
i just get 2 ips for the same server.
i create e new domain name on parallel plesk and in the new domain website file i create e php file with the default forumpath so if you search for .yourdomain.com you are going to yourdomain2.com

He's not asking about redirecting multiple domains to another domain, anyone can do that through a domain manager, htaccess or a simple 301 redirect in the php files. He's asking if each domain can literally be used to navigate through his forum. I've created a mod that does this and takes care of the cookies and SEO, might release it soon. Ill let you know if I do

edit:
if someone want to try this better to take backup first
i new domain no need new database
it is work in the same database

I understand what you are saying here as well Ninja ... but with a redirect you don't need to do any of that above and you just simply use a "redirect" ...

Now if Zachery would of explained earlier, that would be 2 different domains with duplicate content which is what "will" mess with your search rankings ... by using a redirect you don't risk getting hit for duplicate content on 2 different ips or domains ...

So what you don't want to do is actually have a php file that or a mod that will do that, integrate both domains to use the same content ...

Sorry for stating the obvious, but if I understand correctly what eazygreek does - won't he need a second license?

now i have new problem
some users wen try to connect in the forum they have message from panta internet security that page blocked

page contains malware or vulnerability exploitation programs that may infect your computer

No because there will only be 1 db and 1 installation of vb
