We won't be changing anything on this page right now. These settings are fine for getting started until you decide you might like something different in the way post writing defaults.
I have not found a reason to submit posts via email. If I can send an email, I can log in and do a post properly, with all of the tagging and All-In-One SEO entries. If you intend to submit with email, read the instructions at the WordPress site and enter the information here.
The red arrow shows the place where new sites will be entered that we want our blog to "ping" when a new post is published. Pinging is telling a site that a new post has been published. Pinging lets these sites know about the post, and gives your blog exposure on the Web. You will want to enter more sites here. Read the instructions here, and check out the sites in the list. Come back here and enter them later, or do it now if you want to take the time.
