Your best option is to get a random post author which is a user ID so here is a function to do just that: function get_random_author_wpa91320(){ global $wpdb; $id = $wpdb->get_var(” SELECT post_author FROM $wpdb->posts WHERE post_type=”post” AND post_status=”publish” ORDER BY RAND() LIMIT 1 “); return $id; } And once you have that function in … Read more

You probably need to use output buffering, if I understand your question correctly.

You can do it using Widget Context plugin or Widget Logic plugin. They work fine. I prefer Widget Context because it has more flexibility.
After some research and based on the answer from Eugene Manuilov I made a function that adds custom classes to widgets in a specific sidebar (‘sidebar-bottom’ in my case) based on the number of widgets set in that sidebar. This will suit perfectly in horizontal sidebars and themes based on twitter bootstrap that need spanX … Read more
