Right now my homepage has redundancies between featured category posts and the recent articles. I would like to alter my recent articles section so that different articles are visible. I understand that this is possible by adding offset code but I'm not a programmer and need help with this aspect. Is there a way to select which individual articles are visible in the recent articles sections as well? Please see the link to my site below. Also I would like to center the text for the category heading and sidebars. I tried inputing 'text-align: center;' and it didn't work. Please help!
