Under the Email tab, an unique Email Address is assigned to each blog. You can send an email to this email address and the program will automatically read the email and make the blog post. The title for the blog post will be set to the subject of the email and the text of the post will be set to the body of the email.

Under the Email tab, each blog will be assigned a Category Include string, i.e.:
Simply copy and paste the <category name="Sports"> into the body of the email and the post will be published in the categorie.
