OK, well here is the code.

This is the .php file under /includes

PHP Code:

<?php

foreach (explode(',',$userdata->fetch_field('membergroupids')) as $pg_group)
{
    $pg_groupids[$pg_group] = $pg_group;
}
foreach (explode("\n",$vbulletin->options['profile_groups']) as $pg_triple)
{
    list($pg_field,$pg_groupid,$pg_yes) = split(';',trim($pg_triple));
    if ($pg_field and $pg_groupid)
    {
        if (!$pg_yes)
        {
            $pg_yes = 'Yes';
        }
        if ($userdata->userfield[$pg_field] == $pg_yes)
        {
            if (!($pg_groupids[$pg_groupid]))
            {
                $pg_groupids[$pg_groupid] = $pg_groupid;
            }
        }
        else
        {
            if ($pg_groupids[$pg_groupid])
            {
                $pg_groupids[$pg_groupid] = 0;
            }
        }
    }
}
foreach ($pg_groupids as $pg_groupid => $pg_value)
{
    if ($pg_value == 0)
    {
        continue;
    }
    if ($pg_membergroups)
    {
        $pg_membergroups .= ',' . $pg_value;
    }
    else
    {
        $pg_membergroups = $pg_value;
    }
}
$userdata->set('membergroupids', $pg_membergroups);

?>

There are also some plugins and an admincp thing if you want them?
