No, but here's a little mod I just wrote that lets users hide their online status from the privacy page in their profile:
Run the following query in phpmyadmin, or the db managment plugin:
ALTER TABLE `users` ADD `hide_online` TINYINT( 1 ) DEFAULT '0' AFTER `activate_key` ;
Open ./index.php
Find, line 182:
$result = $db->query('SELECT user_id, ident FROM '.$db->prefix.'online WHERE idle=0 ORDER BY ident', true) or error('Unable to fetch online list', __FILE__, __LINE__, $db->error());
Replace with:
$result = $db->query('SELECT o.user_id, o.ident, u.hide_online FROM '.$db->prefix.'online AS o LEFT JOIN '.$db->prefix.'users AS u ON o.user_id=u.id WHERE idle=0 AND u.hide_online=0 ORDER BY o.ident', true) or error('Unable to fetch online list', __FILE__, __LINE__, $db->error());
Open ./profile.php
Find, line 802:
$form = extract_elements(array('email_setting', 'save_pass', 'notify_with_post'));
Replace with:
$form = extract_elements(array('email_setting', 'save_pass', 'notify_with_post', 'hide_online'));
Find, line 808:
if (!isset($form['notify_with_post']) || $form['notify_with_post'] != '1') $form['notify_with_post'] = '0';
Add after:
if (!isset($form['hide_online']) || $form['hide_online'] != '1') $form['hide_online'] = '0';
Find, line 877:
$result = $db->query('SELECT u.username, u.email, u.title, u.realname, u.url, u.jabber, u.icq, u.msn, u.aim, u.yahoo, u.location, u.use_avatar, u.signature, u.disp_topics, u.disp_posts, u.email_setting, u.save_pass, u.notify_with_post, u.show_smilies, u.show_img, u.show_img_sig, u.show_avatars, u.show_sig, u.timezone, u.language, u.style, u.num_posts, u.last_post, u.registered, u.registration_ip, u.admin_note, g.g_id, g.g_user_title FROM '.$db->prefix.'users AS u LEFT JOIN '.$db->prefix.'groups AS g ON g.g_id=u.group_id WHERE u.id='.$id) or error('Unable to fetch user info', __FILE__, __LINE__, $db->error());
