Redirecting old domain.wordpress.com

I started out with a wordpress blog at mydomain.wordpress.com. I just went through the process of installing and importing my blog posts etc to mydomain.com/blog

I want to the former to go to the latter. I could just do a post on the former saying that everything’s been moved, but I’d rather have a true forward in place…

Couldn’t find anything in the forum re: this issue other than the domain mapping upgrade, which isn’t what I’m after…

TIA for a solution…
