Given the following:
1) I own a domain name geekman.com purchased from another registrar.
2) I have or will have purchased the Custom Domain option so that I can point geekman.com to http://geekman2185.wordpress.com.
3) I will establish an external site for a store, such as http://store.yahoo.com/geekman.
How do I set up the Custom DNS records to accomplish this subdomain redirection, while leaving geekman.com pointed to my WordPress blog?
