I'm not gonna make this bad boy, but, I thought I'd somewhat help. For vB3, checkout /includes/functions_forumdisplay.php

Specifically checkout the function, "fetch_dot_threads_array":

PHP Code:

// ###################### Start getDotThreads #######################
// --> Queries a list of given ids and generates an array of ids that the user has posted in
function fetch_dot_threads_array($ids)
{
    global $DB_site, $bbuserinfo, $vboptions;

    if ($ids AND $vboptions['showdots'] AND $bbuserinfo['userid'])
    {
        $dotthreads = array();
        $mythreads = $DB_site->query("
            SELECT COUNT(*) AS count, threadid, MAX(dateline) AS lastpost
            FROM " . TABLE_PREFIX . "post AS post
            LEFT JOIN " . TABLE_PREFIX . "deletionlog AS deletionlog ON (post.postid = deletionlog.primaryid AND type = 'post')
            WHERE post.userid = $bbuserinfo[userid] AND
            post.visible = 1 AND
            post.threadid IN (0$ids) AND
            deletionlog.primaryid IS NULL
            GROUP BY threadid
        ");

        while ($mythread = $DB_site->fetch_array($mythreads))
        {
            $dotthreads["$mythread[threadid]"]['count'] = $mythread['count'];
            $dotthreads["$mythread[threadid]"]['lastpost'] = vbdate($vboptions['dateformat'], $mythread['lastpost'], true);
        }

        return $dotthreads;
    }

    return false;

} 


This function returns an array of thread ids the user posted in. Anyway, messing with that somewhat is a big start.
