[PAYH] - Domain pointing at a subfolder

[#1]

HI All
I have a Domain http://www.dhea-forum.org.uk what is hosted by 123-reg I want to point it at a subfolder http://dyslexia.plushost.co.uk/forum/ can this be done?  If I Change Nameservers to:
Nameserver 1: ns1.force9.net
Nameserver 2: ns2.force9.net
Then send a Ticket to Force 9 Technical Support letting them know what I am wanting to do!
Will that work?

If you do that, we will be able to add the domain as its own domain on to the Plesk control panel.

Do I need to send a Ticket to Force 9 Technical Support?  or can you sort it out for me?

As you can see from the Screen shot the Domain dhea-forum.org.uk is not connected to PlusHost on my account.
It is not pointing to the folder "forum" the Domain dhea-forum.org.uk it is not set up properly.
On my Force9 account all I need to do is get the Domain pointed at the folder that I want the Domain to go to.
I am sorry to say that the way that I had it set up on 123-reg was better plus it was not costing £25 a year, it was Free.
So the Question now is am I going to be charged £25 for this if I move the Domain dhea-forum.org.uk back to 123-reg ?

Thats due to you having the domain as an alias, so if you click on to show aliases you will be able to see the domain there.
You then have an htaccess file that redirects that domain to the address.
This was set up as you requested for it to work via the ticket you raised.
