Is it possible for me to 301 redirect the whole of my name.wordpress.com blog to a www.blog.com domain?
yes u need to pay $10 per yr. to them.....for name.wordpress.com blog to a www.blog.com but the blog will be hosted with them....i.e. u can't have control- no ads...nothing.....only the domain will redirect and people would know your new domain...see their admin panel for details to add domains...
