Now many of you who read the title may get confused. You are saying I already have a domain name with this hosted blog platform. Well, the key is the term “hosted blog”.
Remember that WordPress.com is a Hosted Blog Platform. WordPress.org is a self-hosted blog platform.
With the WordPress.com (hosted) platform your blog address will have “username.wordpress.com. However, when you go to a self hosted platform you will need domain name that you purchase. Your url will read username.com/org/net/info, etc
Now, the good news is that if you are on hosted WordPress.com you can still have your own domain name WITHOUT the .wordpress.com at the end. All you have to do is go to UPGRADES on your Administration panel.
It is the very last, I mean very last option on panel. Click it on and for a small fee you can upgrade. You will first need to purchase a domain name and then place it the the field indicated.
Ok, now if you want a video just let me know. Hope this helps.
