How do I create a new Manufacturer URL?

I tried searching for the answer to this on the forums, but couldn't find any answer.

I'm trying to add a new Manufacturer and the corresponding link (URL).
Here is the process I am doing:
Catalog->Manufactuers->Insert

then, I went to System->Design->Banners->Manufacturers

But, there isn't any place where I can see the 'Link". So in my list of Manufacturers, just has the link to the homepage.
You can see it here: http://www.wheysupply.com

The Manufacturers that have a link, it's because I just re-used the pre-existing URLs from the installation.

How do I create NEW manufacturer URLs.

Any advice would be MUCH appreciated.

Thanks.

at the bottom of your site, there is a link named Brands , open it all brands are listed there, open any brand and copy its link, then paste it in banner. for eg. for Nutri-supreme its http://www.wheysupply.com/index.php?rou ... turer_id=5

also you can use seo urls from catalog >> manufacturer
