use the script in /spider/connect/<callsign> to effect the 'chat' exchange
necessary to traverse the network(s) to logon to the cluster <callsign>.
+=== 9^CATCH <node call> All|[<msgno> ...]^Mark a message as sent
+=== 9^UNCATCH <node call> All|[msgno> ...]^Unmark a message as sent
+When you send messages the fact that you have forwarded it to another node
+is remembered so that it isn't sent again. When you have a new partner
+node and you add their callsign to your /spider/msg/forward.pl file, all
+outstanding non-private messages will be forwarded to them. This may well
+be ALL the non-private messages. You can prevent this by using these
+commmands:-
+
+ catch GB7DJK all
+ catch GB7DJK 300 301 302 303
+
+and to undo what you have just done:-
+
+ uncatch GB7DJK all
+ uncatch GB7DJK 300 301 302 303
+
+which will arrange for them to be forward candidates again.
