    //to be able to use this outside the loop
    if ( have_posts() ) { the_post(); rewind_posts(); }

    get_sidebar('cat1');
    //gets sidebar-cat1.php

    edit your wp-config.php file.
    To limit post revisions, just add the following lines:

    define('AUTOSAVE_INTERVAL', 3600); // Auto-saves on 1 hour interval

    Change author attribution on all posts

    use phpmyadmin with the following commands to modify your WordPress database, don’t forget to create a backup before running any command throught phpmyadmin.

    The first thing to do is getting the IDs of WordPress users. Once logged in phpmyadmin, insert the following SQL command:

    SELECT ID, display_name FROM wp_users;

    Right now, phpmyadmin displayed a list of WordPress users associated with their IDs. Let’s say that NEW_AUTHOR_ID is the ID of the “new” author, and OLD_AUTHOR_ID is the old author ID.

    UPDATE wp_posts SET post_author=NEW_AUTHOR_ID WHERE post_author=OLD_AUTHOR_ID;

    Set post expiration date/time

    replace your current WordPress loop by this “hacked” loop:

    <?php
    if (have_posts()) :
    while (have_posts()) : the_post(); ?>
    $expirationtime = get_post_custom_values('expiration');
    if (is_array($expirationtime)) {
    $expirestring = implode($expirationtime);
    }

    $secondsbetween = strtotime($expirestring)-time();
    if ( $secondsbetween > 0 ) {
    // For exemple...
    the_title();
    the_excerpt();
    }
    endwhile;
    endif;
    ?>

    create a custom field, then give it expiration as a key and your date/time (format: mm/dd/yyyy 00:00:00) as a value.
