-<P>One of the more important things a cluster sysop needs to do is to get
-information to his users. The simplest way to do this is to have a banner
-that is sent to the user on login. This is know as a "message of the day"
-or "motd". To set this up, simply create a file in /spider/data called motd
-and edit it to say whatever you want. It is purely a text file and will be
-sent automatically to anyone logging in to the cluster.
-<P>
-<H2><A NAME="ss8.2">8.2 Downtime message</A>
-</H2>
-
-<P>If for any reason the cluster is down, maybe for upgrade or maintenance but
-the machine is still running, a message can be sent to the user advising them
-of the fact. This message lives in the /spider/data directory and is called
-"offline". Simply create the file and edit it to say whatever you wish.
-This file will be sent to a user attempting to log into the cluster when
-DXSpider is not actually running.
-<P>
-<H2><A NAME="ss8.3">8.3 Other text messages</A>
-</H2>
-
-<P>You can set other text messages to be read by the user if they input the file
-name. This could be for news items or maybe information for new users.
-To set this up, make a directory under /spider called <EM>packclus</EM>.
-Under this directory you can create files called <EM>news</EM> or <EM>newuser</EM>
-for example. In fact you can create files with any names you like. These can
-be listed by the user with the command ....
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-show/files
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>They can be read by the user by typing the command ....
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-type news
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>If the file they want to read is called <EM>news</EM>. You could also set
-an alias for this in the Alias file to allow them just to type <EM>news</EM>
-<P>
-<P>You can also store other information in this directory, either directly or
-nested under directories. One use for this would be to store DX bulletins
-such as the OPDX bulletins. These can be listed and read by the user.
-To keep things tidy, make a directory under /spider/packclus called
-<EM>bulletins</EM>. Now copy any OPDX or similar bulletins into it. These
-can be listed by the user in the same way as above using the <EM>show/files</EM>
-command with an extension for the bulletins directory you have just created,
-like this ....
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-show/files bulletins

-<P>
-<P>An example would look like this ....

-<P>You can see that in the files area (basically the packclus directory) there is a
-file called <EM>news</EM> and a directory called <EM>bulletins</EM>. You can
-also see that dates they were created. In the case of the file <EM>news</EM>,
-you can also see the time it was last modified, a good clue as to whether the
-file has been updated since you last read it. To read the file called
-<EM>news</EM> you would simply issue the command ....

+<P>I think this is fairly self explanatory. It is simply a list of subject

+<H2><A NAME="ss8.2">8.2 Filtering DX callouts</A>
</H2>
-<P>DXSpider receives all and any mail sent to it without any alterations needed
-in files. Because personal and bulletin mail are treated differently, there
-is no need for a list of accepted bulletin addresses. It is necessary, however,
-to tell the program which links accept which bulletins. For example, it is
-pointless sending bulletins addresses to "UK" to any links other than UK
-ones. The file that does this is called forward.pl and lives in /spider/msg.
-At default, like other spider files it is named forward.pl.issue. Rename it
-to forward.pl and edit the file to match your requirements.
-The format is below ...
+<P>In the same way as mail, there are some types of spot we do not wish to pass on
+to users or linked cluster nodes. In the /spider/data directory you will find
+a file called baddx.pl.issue. Rename this to baddx.pl and edit the file. The
