Do you want to delete your blog?
You can delete your entire blog, but you have to keep in mind that this will permanently delete your blog including all your posts.
To delete your entire blog, just go to Settings | Basic. Then click Delete Blog and confirm by clicking OK.
If you've accidentally deleted your blog and want it back, you can restore your blog within a certain period of time after deletion. You just need to go to your Dashboard, where your blogs are listed, click "Show all,".
Your deleted blog will appear in the list, with the option "Undelete this blog." Click this option and everything will be back to normal.
