Right. I have a domain ready to be applied from an external registrar (ie. not wordpress), and soon will be paying the $10 needed so that I can use it with my blog.
But I have one question - how long will that $10 last me? Does it mean that I can use a domain name with my blog forever, or does it expire after a certain amount of time. I am well aware that the domain itself, will expire, and that's no problem.
Also, how many domains will this allow me to use? So, if I wanted both http://www.A.com and http://www.B.com to be pointing to my domain, but they were actual domains (not domain masking services), then could I register both to the same blog?
