In mylinks/xoops_version.php look for:
$modversion['hasMain'] = 1;
$modversion['sub'][1]['name'] = _MI_MYLINKS_SMNAME1;
$modversion['sub'][1]['url'] = "submit.php";
$modversion['sub'][2]['name'] = _MI_MYLINKS_SMNAME2;
$modversion['sub'][2]['url'] = "topten.php?hit=1";
$modversion['sub'][3]['name'] = _MI_MYLINKS_SMNAME3;
$modversion['sub'][3]['url'] = "topten.php?rate=1";
remove the ['sub'] that you want to get rid of.
EDIT "I forgot to mention you need to update the module after"
Hope that helps.
