Bill,

That's just brilliant! Thank you.

If anyone's interested...

file: skin1/mail/html/order_invoice.tpl

FIND:

{foreach from=$_userinfo.additional_fields item=v}
{if $v.section eq 'S'}
		<tr>
			<td><b>{$v.title}:</b></td>
        	<td>{$v.value}</td>
		</tr>
	{/if}
{/foreach}

AFTER, insert:

{if $order.login|strpos:'customer-'===0}
{else}
<tr>
<td><strong>Username:</strong></td><td>{$order.login}</td>
</tr>
{/if}

Replace 'customer' with whatever you've named your anonymous customers... in config.php

$anonymous_username_prefix="customer";

Another very nice addition to the customer invoice.

Thanks Bill!
