OK, I missing something here.  What name sequence are you talking about?

and as for missing names on form elements, I have all input types named. 
Especially the submit buttons.

FYI, here's the essential form elements and the albatross glue code I used to 
connect to my data extraction code.


<h2>Instructions:</h2>

<p>Red messages strongly suspected to be spam.  Green messages are strongly 
suspected to be not spam.</p>

<p>Your job is: Correct message with wrong classification.</p>


<p>There are only two ways a message can have the wrong classification.  Either:

<ul>
<li>The email <b>is</b> spam, and was classified as good e-mail</li>
<li>Or the email <b>is not</b> spam, and was classified as spam.</li>
<li>If you are not sure, check the message detail by following the subject 
link.</li>
</ul>

In order to change the classification, press the button on the line
labeled "change classification".  Repeat until all messages have been
processed.
