-<P>In earlier versions of Spider, all the processes were Perl scripts. This was fine but with a lot of users your computer
-memory would soon be used up. To combat this a new client was written in "C". This client only works for <EM>incoming</EM>
-connects at the moment. Before you can use it though it has to be "made". CD to /spider/src and type <EM>make</EM>. You
-should see the output on your screen and hopefully now have a small C program called <EM>client</EM>. Leave it in this
-directory.

+
+<P>In the /spider/msg directory you will find a file called badmsg.pl.issue. Rename
+this to badmsg.pl and edit the file. The original looks something like this ....

+# the list of regexes for messages that we won't store having
+# received them (bear in mind that we must receive them fully before
+# we can bin them)
+
+
+# The format of each line is as follows
+
+# type source pattern
+# P/B/F T/F/O/S regex
+
+# type: P - private, B - bulletin (msg), F - file (ak1a bull)
+# source: T - to field, F - from field, O - origin, S - subject
+# pattern: a perl regex on the field requested
+
+# Currently only type B and P msgs are affected by this code.
+#
+# The list is read from the top down, the first pattern that matches
+# causes the action to be taken.
+
+# The pattern can be undef or 0 in which case it will always be selected
+# for the action specified

+<P>
+<P>I think this is fairly self explanatory. It is simply a list of subject
+headers that we do not want to pass on to either the users of the cluster or
+the other cluster nodes that we are linked to. This is usually because of
+rules and regulations pertaining to items for sale etc in a particular country.

+<H2><A NAME="ss2.2">2.2 Filtering words from text fields in Announce, Talk and DX spots</A>
+</H2>
+
+<P>From version 1.48 onwards the interface to this has changed. You can now
+use the commands <EM>set/badword</EM> to add words that you are not prepared
+to see on the cluster, <EM>unset/badword</EM> to allow that word again and
+<EM>show/badword</EM> to list the words that you have set.
+<P>
+<P>If you have a previous <EM>/spider/data/badwords</EM>, the first time you start
+the node, it will read and convert this file to the new commands. The old style
+file will then be removed.
+<P>
+<H2><A NAME="ss2.3">2.3 Stopping (possibly bad) DX Spots from Nodes or Spotters</A>
+</H2>
+
+<P>
+There are a number of commands that control whether a spot progresses
+any further by regarding it as "bad" in some way.
+<P>
+<P>A DX Spot has a number of fields which can checked to see whether they
+contain "bad" values, they are: the DX callsign itself, the Spotter and
+the Originating Node.
+<P>
+<P>There are a set of commands which allow the sysop to control whether a
+spot continues:-
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+set/baddx
+set/badspotter
+set/badnode
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>These work in the same as the <EM>set/badword</EM> command, you can add
+any words or callsigns or whatever to the appropriate database. For
+example, to stop a spot from a particular node you do:
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+set/badnode gb7djk gb7dxc
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>a bad spotter:
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+set/badspotter b0mb p1rat nocall
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>and some bad dx:
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+set/baddx video wsjt
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>You can remove a word using the appropriate unset command
+(<EM>unset/baddx, unset/badspotter, unset/badnode</EM>) or list them
+using one of <EM>show/baddx, show/badspotter</EM> and
+<EM>show/badnode</EM>.
