Ok, just went through the files and tested the display on my garden site...

In admin/membermanage.php Find:
Code
if ($user['USER_MEMBERSHIP_LEVEL'] == "Administrator") {
	$tabs = array(
		"{$ubbt_lang['VIEW']}" => "",
		"{$ubbt_lang['REG_QUE']}" => "",
		"{$ubbt_lang['DISP_QUE']}" => "",
		"{$ubbt_lang['BAN_LIST']}" => "",
		"{$ubbt_lang['ADD_USER']}" => "",
	);
} else {
	$tabs = array(
		"{$ubbt_lang['VIEW']}" => "",
	);
}

Replace with:
Code
if ($user['USER_MEMBERSHIP_LEVEL'] == "Administrator") {
	$tabs = array(
		"{$ubbt_lang['VIEW']}" => "",
		"{$ubbt_lang['REG_QUE']}" => "",
		"{$ubbt_lang['DISP_QUE']}" => "",
		"{$ubbt_lang['BAN_LIST']}" => "",
		"{$ubbt_lang['ADD_USER']}" => "",
	);
} elseif(($user['USER_MEMBERSHIP_LEVEL'] == "GlobalModerator") || ($user['USER_MEMBERSHIP_LEVEL'] == "Moderator")) {
	$tabs = array(
		"{$ubbt_lang['VIEW']}" => "",
		"{$ubbt_lang['REG_QUE']}" => "",
	);
} else {
	$tabs = array(
		"{$ubbt_lang['VIEW']}" => "",
	);
}

In templates/default/admin/membermanage.tmpl Find:
Code
UBBTPRINT;

if ($user['USER_MEMBERSHIP_LEVEL'] == "Administrator") {

echo <<<UBBTPRINT

MOVE IT to be Above:
Code
<!-- Start Tab: 2 -->

If you want to remove the admin check completely from the template, the closing bracket for the find line is after:
Code
<!-- End Tab: 4 -->
