I think @skylinebaptistchurch is a little confused about the difference between a post and a page read this article: http://en.support.wordpress.com/post-vs-page/
By default a wordpress site's "home page" is a list of your most recent posts. You can change it so the home page is a normal static page and making a different page display all the latest posts. by following these instructions: http://en.support.wordpress.com/pages/front-page/
Categories allow you to sort your posts. When you create or edit a post you can label it with a category. These category labels will allow you to make various feeds that only contain posts labeled with the specific category.
For example right now http://skylineconnect.org/feed/ would feed every post and the kitchen sink to subscribers.
After creating posts with the category "podcast" http://skylineconnect.org/podcast/feed/ would only feed the posts you categorized as "podcast" to subscribers.
