Using Smugmug as the Client Gallery portion of website

[CWN]

Hello - I'll try to explain what I want to do and if someone could help me *in English* I would be most appreciative.

I have a pro account here at smugmug. It is www.cwnphotography.smugmug.com (http://www.cwnphotography.smugmug.com)

I registered a domain name with Joker.com - www.cwnphotography.com (http://www.cwnphotography.com) and have it pointed (CNAME?) to my smugmug section.

Here's what I want to do -

put together a new website and host it somewhere, with a "client galleries" link to http://cwnphotography.smugmug.com/Client%20Galleries[/URL]. I think I have that part figured out - but what I don't have figured out is this:

I have set up categories for customers using their last name. For example, I have a wedding gallery at http://cwnphotography.smugmug.com/moran

Once I switch to a webhoster and move [URL="http://www.cwnphotography.com"]www.cwnphotography.com (http://www.cwnphotography) to them - I want to be able to have my customers still be able to type in their custom link and have it go to their gallery.

I can't figure out exactly what this service is called - URL Forwarding, path forwarding, etc??? All I need to know is what this is formally called and if there are webhosters that do this? It doesn't look as if joker.com does this - so that's why I believe I have to transfer everything to a new registrar.

Please help! Thank you very much in advance!!!
