Thanks, Kent. The problem with some sites is that contravene what we consider conventions, such as not including the flow of physical goods in a DFD. I don&#39;t encourage my kids to do much extra-curricular research into such tools since they often end up really confused about what is &#39;legitimate&#39;.<br>

<br>I do, however, do a lot of such research myself, which just makes ME confused  :-(<br><br><div class="gmail_quote">On 29 March 2012 08:51, Kent Beveridge <span dir="ltr">&lt;<a href="mailto:kbeveridge@stbc.vic.edu.au">kbeveridge@stbc.vic.edu.au</a>&gt;</span> wrote:<br>
