I’m considering using TypePad (http://www.typepad.com/) to host my weblog. TypePad supports a feature called domain mapping, where my domain can be pointed at their servers. In order to use this feature, my registrar must support custom DNS services–I need control over the DNS records that describe my domain, and I must have the ability to create and modify A, MX, and CNAME records. Do you offer such a service? Please send me more details on how it works and how I can turn it on for my account.
