That is more so Joomla related questions as the Template only stylizes the site. You can add an article via the Joomla Backend under the Article Manager. Featured Articles are those that appear on the Front Page in the Content area of the Layout. Modules can be used as Custom HTML and assigned to their corresponding positions. You can read some of the documentation for Joomla here:http://docs.joomla.org/Portal:Beginners#Absolute_Beginners_Guide_to_Joomla.21
If you have any specific questions I will be happy to answer them here.
Okay here are my specific questions:
1) I know how to add an article, but like in your demo, how do I make it have an image with the article like in the slider you have?
2) How do I remove the text underneath the menus, for example return to home under the home button?
3) How do I make new articles show up in the NBA - Latest News, NFL - Latest News, MLB - Latest News columns
4) Also why in firefox are the twitter & facebook icons not showing at the top? Chrome it is showing and working fine.
4b) In firefox, I can't click save / save or close in this theme but in Chrome it works fine...
5) How do I edit FAN UPDATES, quick links, in the media, and shop online?
