By default, WordPress only allow authors to edit their own posts. You can change these settings and give author capabilities including editing other authors posts.
Instructions: Add the following code to the functions.php file of your WordPress theme.
This is a list of other capabilities that can be used. To add more than one capability, just add a new line $role->add_cap( 'new_cap_name' );.
function add_theme_caps() {
$role = get_role( 'author' );
$role->add_cap( 'edit_others_posts' );
}
add_action( 'admin_init', 'add_theme_caps');
You may also enjoy showing the authors posts in the edit list.
