On a different fields it is also possible you deactivate the function of WP; as example comments and author:

add_action( 'admin_init', 'fb_deactivate_support' );
function fb_deactivate_support() {
    remove_post_type_support( 'post', 'comments' );
    remove_post_type_support( 'post', 'author' );
}


the post-string is for the post_type, you can also use this for all post types via:

foreach ( get_post_types() as $post_type ) {
    remove_post_type_support( $post_type, 'comments' );
} 




How to remove a column from the Posts page
I tend to stay at smaller boutique hotels or local apartments when I visit a city but recently due to some credit card issues I will need to depend on prepaid Visa.  But I noticed when I try to shop online a lot of retailers don't accept prepaid credit cards so I'm thinking hotels would be even stricter.  Is there a list somewhere of countries or particular hotel chains than ban prepaid cards? If so, how does one book online or reserve a room without a card?  Do all hotels worldwide accept cash?
