I have installed my forum (vBulletin) on a subdomain but I also have another URL linking to the forum


http://forums.MyDomain.co.uk (this is the one I want to use)

Now I want to redirect users who use the URL http://www.manchesters-armed-defenders.co.uk to http://forums.MyDomain.co.uk

This is where I need help as I have been looking around the web and it says that I have to add some code to the .htaccess file but I dont know what or how to do so?

can anyone help please?
