Topic: Go back in time (e.g. reset post indicators)
ok i think a couple people wanted this (and so did I 
) basically it allows you to go back a set number of hours per click.
open misc.php
find
else
message($lang_common['Bad request']);before add
else if (isset($_GET['go_back']))
{
$go_back_time = $pun_user['last_visit'] - (3600 * intval($_GET['go_back']));
$db->query('UPDATE '.$db->prefix.'users SET last_visit='.$go_back_time.' WHERE id='.$pun_user['id']) or error('Unable to go back in time', __FILE__, __LINE__, $db->error());
redirect('index.php', 'Gone Back '.$_GET['go_back'].' hours');
}open index.php
find
echo "\t\t\t\t".'<dd><a href="search.php?action=show_user&user_id='.$pun_user['id'].'">'.$lang_common['Show your posts'].'</a></dd>'."\n\t\t\t".'</dl>'."\n";replace with
echo "\t\t\t\t".'<dd><a href="search.php?action=show_user&user_id='.$pun_user['id'].'">'.$lang_common['Show your posts'].'</a></dd>'."\n";
echo "\t\t\t\t".'<dd><a href="misc.php?go_back=24">Go Back 24 Hours</a></dd>'."\n\t\t\t".'</dl>'."\n";that will add a go back 24 hours button to the homepage and you can use misc.php?go_back=<hours> replacing <hours> with the number of hours you want to go back , i don't think there are any "side effects" of this but there could be if you have any problems post here and as usually make a backup
