As I said there, you have only one published post at peoplefortsmith.com. As soon as you publish more, they will appear on the blog grid.
Your site is hosted at WordPress.com, but these forums are for folks running the WordPress software on their own hosting. If you need further help with your WordPress.com site, please post in the WordPress.com forums. You can also access live chat when available here:
