<h2>Next add assignees</h2><blockquote>
<p>
Back to the "Tickets" admin page, and click "Common".  Add something like this:
<pre>
set assigned_choices {
  unassigned
  tom
  dick
  harriet
}
</pre>
Obviously, choose names corresponding to the logins on your system.  The
'unassigned' entry is important, as it prevents you from having a NULL in that
field (which causes problems later when editing).
</p>
</blockquote>

<h2>Now modify the 'new ticket' page</h2><blockquote>
<p>
Back to the "Tickets" admin page, and click "New Ticket Page".  This is a little
more tricky.  Edit the top part:
<pre>
  if {[info exists submit]} {
     set status Open
     set opened_by $login
	 set assigned_to "unassigned"
     submit_ticket
  }
</pre>
Note the "set opened_by" bit -- that will automatically set the "opened_by"
field to the login name of the bug reporter.  Now, skip to the part with "EMail"
and modify it like so:
<pre>
