I am planning to register new domain name for my block http://techtooltip.wordpress.com. I want the new URL to be http://techtooltips.com. I searched the forum but couldn't find definitive answers for following two questions.
1. After registration and mapping, can the blog be accessed by both old and new URL?
2. If I don't want the new domain name for any reason (cancel/expired registration and mapping), can the blog will still be accessed with old URL (http://techtooltip.wordpress.com) after (cancellation/expiry).
Thanks in advance for your time and support.
The blog I need help with is techtooltip.wordpress.com.
