i have create free blog on the word-press site.every thing is fine but i have added wrong domain name(spelling).please suggest your comment how to change my domain spelling??
There is no way, you need to buy the domain with the right name. Or you mean you have a blog at .wordpress.com?
You'll need to register on wordpress.com for the right subdomain and then just abandon the one that is wrong.
Grab other domain name. As this is free of cost CMS, so you can make as many blogs as you want on WordPress.com.
I don't think domain providers accepts renaming purchased domain names. You have to be careful creating your domain name next time - lol
To summarize, there are 2 options: - you registered for a subdomain on the WordPress.com site. If that is the case simply register the correct subdomain and start from there - you registered a standalone self-hosted domain. If that is the case contact your domain registrar and explain the case, asking to delete the wrong and register the correct one. Most registrars do have a grace deletion period so if you have discovered your error pretty quick, chances are they will do that for you (even possibly with no extra charge added)
If it is sub-domain on wordpress site, it cannot be changed. If you mispelled a domain name, you cannot rectify it but you will have to register the correct domain name if it is available.
