I am trying to map an existing domain registered through register.com to my wordpress.com blog. The existing domain is http://artscrawlabq.org/ and the wordpress.com blog is http://abqartscrawl.wordpress.com/. I changed the DNS servers three days ago and each time I try to add the domain to my blog I get the message 'wordpress.com can't register artscrawlabq.org'. What am I missing?
The blog I need help with is abqartscrawl.wordpress.com.
