Redirect domain to .Mac account?

I have an account with Namecheap.com that has my family's blog address. I want to host the blog on my .Mac account so that I don't have to give out the long URL to people. I have it set, at Namecheap.com, to forward to the blog and mask the URL, so that when you type in the domain name, it goes to the .Mac site and the address bar remains the original domain name.

However, I want to be able to view full masked addresses in the addressbar. For instance, instead of it always saying www.mydomain.com, I want it to be able to say www.mydomain.com/maber/blog1.html, etc. Anyone know how to do this?

Thank you!

It seems like what I would need is to give the .Mac DNS to Cheapnames. But where can I find those nameservers?

ask cheapnames to point www.mydomain.com at the root of your .Mac acount.
