How to give “author” user role appropriate capabilities to add PollDaddy polls? WordPress multisite

Open the file “polldaddy.php” and look near the first few dozen lines for this:

$this->is_admin               = (bool) current_user_can( 'manage_options' );

Change that to

$this->is_admin               = (bool) current_user_can( 'edit_posts' );

That would in theory grant authors and above the same access as an admin – you have to test yourself to be sure. See the admin_menu() function for where the menus are set up along with required permission levels.
