Blogger allows users to send emails to their blog which in turn get posted as a blog in itself.
say an email address like firstname.lastname@example.org. It gets published to john.blogspot.com. :)
So here is my first email blog. Dint want it to be anything weird. Just an explanation of how it works.
If you want to mail in your blogs through emails. Go to "Settings>Email>Mail-to-Blogger Address>" in blogger.com after you sign in.
Here give options of email you want. only the second half can be changed. Check the Publish button to allow the blog to be published.
