Thanks.

Anthony that is almost perfect for me except I don't have control over which forums you can hide.

This was the plugin code Xenon posted that doesn't work for me:

// Exclude Forums except direct link to thread
if ($vbulletin->userinfo['fieldxx'] != 0 AND THIS_SCRIPT != 'showthread' AND THIS_SCRIPT != 'attachment')
{
    $excludeforums = array();
    if ($vbulletin->userinfo['fieldxx'] & (1 << 0)) // first checkbox
    {
        $excludeforums = array_merge($excludeforums, array(xy, xy, xy, xy));
    }
    if ($vbulletin->userinfo['fieldxx'] & (1 << 1)) // second checkbox
    {
        $excludeforums = array_merge($excludeforums, array(za, za, za, ta));
    }
...
    foreach ($excludeforums AS $fid)
    {
        $vbulletin->userinfo['forumpermissions']["$fid"] = 0;
    }
}
