I had a recent post to my other site, Mad About Madrid asking for more details on how to go about domain name mapping - I think Marketing Tom is a better forum than the other site to discuss this issue. Here is a definition of domain name mapping from TypePad (the people who power this blog):
Domain Mapping is the process of pointing a registered domain name to a TypePad, weblog or photo album. Domain mapping is more than domain forwarding, because your permalinks and URL contain the address of your domain (www.example.com), and not your TypePad sub-domain (example.typepad.com).
In my case the domain name www.marketingtom.com maps to madrid.blogs.com/marketing_tom and all sub-pages are displayed under www.marketingtom.com. Since I last spoke about domain name mapping, the control panel on Godaddy has changed. This is the new procedure you now need to follow:
Once you are in your control panel you select 'manage domains'
Click on the domain name that you need to set domain name mapping up on
In the bottom right-hand side of the page click 'Total DNS Control'. Then click Manage DNS Zone File' and add in the details.
From here, you can following the instructions on TypePad Domain Mapping
