Deleting Posts from Blogger Account:
If you're able to sign in to your Blogger account but can't see your blog on your dashboard, you may have multiple Google Accounts and are most likely logged in to the wrong one. Try logging in with each email address that you may have used to create a Google Account. If you don't remember which email address or URL you used to sign up, just go to www.blogger.com/forgot.g and enter the URL of the blog you're trying to gain access to. You'll be given a hint about which email address is associated with that...
