Hi, Robin

Hmmm...

user is a variable that is assigned when you first login.  

The source of the bottom frame when 'Jim' is logged in looks like:

<CENTER><TABLE CELLSPACING=0 CELLPADDING=0>
<TR><TD>
<nobr><FORM ACTION="formframe" METHOD="POST">
Your message: <input name=user type=hidden value="Jim">
<textarea name=message rows=3 cols=50></textarea>
<input type=submit value="Post Message">
</form></nobr>
</TD><TD>
<nobr><FORM ACTION="formframe" METHOD="POST">
<input name=user type=hidden value="">
<input type=submit value="Logoff">
</form></nobr>
</TD></TR>
</TABLE></CENTER>

so user should be there in REQUEST.form, because it is passed in the
hidden field.

BUT the beginning of formframe only checks to see if there is
[somewhere!] a non-nil variable called message,  AHA!  

So, Robin, I will bet you have a 'message' on the acquisition path.

If so, the right answer is:

The first part of formframe should read: 

<dtml-if message>
  <dtml-if user>
    <dtml-call "REQUEST.set('dt',ZopeTime())">
    <dtml-call "REQUEST.set('id',dt.strftime('%Y%m%d%H%M%S')+user)">
    <dtml-call "ChatItemClass_add(_.None, _, NoRedir=1)">
  </dtml-if>
</dtml-if>

since we need both user and message here.

Let me know if this works.  My take-home lesson in this is that I
definitely should use less popular variable names in an acquisition
system.

Shall we call this kind of bug "Spanish Acquisition"?  
It has a Pythonish ring...
And few of us really expect it...
