+  QUICK GUIDE
+
+  Mailing-lists on this server (\dml.address):
+
+  \getlists;[ex:=\dml.listname]
+
+  Mails received from the server ALWAYS starts with the listname
+  enclosed in stars (*). For example,
+
+  *[ex]\[7\]* hello world
+
+  means you've received a message from the list '[ex]' with
+  subject 'hello world'. The message is identified by its
+  message number, in this case 7.
+
+  EXAMPLES
+
+  To post a new message on '[ex]' with subject 'hello world',
+  mail to \dml.address with subject
+
+  new [ex] hello world
+
+  To post a new message on a particular message number, e.g. 7,
+  mail to \dml.address with subject
+
+  new [ex]\[7\] hello world
+
+  Note that message number 1 is the message root, and is the same
+  as issuing new without the \[\].
+
+  To reply to a message from the list, use 'reply' in your mailing program,
+  but DO NOT REMOVE anything before the subject. The server will
+  insert the appropriate 'Re:'. For instance, replying to the first example
+  above would normally give a reply-subject in your mailprogram like
+
+  Re: *[ex]\[7\]* hello world
+
+  which will be sent from the server as
+
+  *[ex]\[n\]* Re: hello world
+
+  where n is some new number assigned to your message.

+  HELP ON USAGE OF THE *\dml.listname* MAILING LIST AT \dml.address.
+
+  The address handles multiple mailinglists, and takes commands on the form:
+  
+  <cmd> <list>\[<node>\] <subject>
+  or
+  <cmd> *<list>\[<node>\]* <subject>
+  
+  where <cmd> is a command, <list> is a mailinglist,
+  <node> is a message number, and <subject> is the subject
+  line. The brackets \[\] should however be there as is.
+
+  Mailing-lists on this server (\dml.address):
+
+  \getlists
+  
+  You are \user.name, and your user name at \dml.address
+  is \user.email. You may have clearance to several of
+  the lists above.
+  \if(\dml.listname eq "demo"){
+    \n;
+    This is a demo mailing list and will not work to send mails to.
+    You will need to know the name of a list to which you belong.
+  }
+  Commands are not case sensitive. Available commands <cmd> are:
+  
+  HELP \dml.listname
+  
+  Displays this message.
+  
+  WHO \dml.listname\[<node>\]
+  
+  Retrieve which people are registered at the list.
+  If a node number is given, it tells which people
+  will receive a new message from that node.
+  Note that this command may be restricted on some lists.
+  
+  SILENT \dml.listname\[<node>\]
+  
+  Adds a new message to message number <node> on \dml.listname,
+  without broadcasting.
+  
+  NEW \dml.listname\[<node>\] <subject>
+  
+  Adds a new message to message number <node> on \dml.listname,
+  and broadcasts to \dml.listname.
+  
+  REPLY \dml.listname\[<node>\] <subject>
+  
+  Replies to message number <node> on \dml.listname.
+  Possible acronyms are Re, Re:, Sv, Sv:.
+  Note that this command is issued when you do
+  a normal reply, whether it be on a swedish or
+  american mail program.
+  
+  OPEN \dml.listname\[<node>\]
+  
+  Opens a <node>. When a <node> is open, you recieve
+  broadcast messages descending from that <node>.
+  
+  CLOSE \dml.listname\[<node>\]
+  
+  Closes a <node>. When a <node> is closed, you do not
+  recieve the broadcast messages descending from that <node>.
+  The obvious usage of this command is to turn off
+  uninteresting of lengthy threads. Also, since everything
+  added to this node will pass unnoticed, it may be used
+  to structure e.q. news in topics, together with the
+  SILENT command.
+  
+  MAIL \dml.listname\[<node>\]
+  
+  Retrieve message number <node> from \dml.listname.
+  This command may not serve certain messages on the basis of your
+  clearance and when you first entered the list.
+  
+  \if(\dml.listname ne "demo"){
+    To get additional help on how to use this system, how to
+    view or protect message trees, you may visit the
+    \dml.http/ web page. Of course the commands listed
+    above can be issued from there as well. You PIN code
+    at the server is \user.pin.
