+=== 9^SET/REGISTER <call> ...^Mark a user as registered
+=== 9^UNSET/REGISTER <call> ...^Mark a user as not registered
+Registration is a concept that you can switch on by executing the
+
+ set/var $main::regreq = 1
+
+command (usually in your startup file)
+
+If a user is NOT registered then, firstly, instead of the normal
+motd file (/spider/data/motd) being sent to the user at startup, the
+user is sent the motd_nor file instead. Secondly, the non registered
+user only has READ-ONLY access to the node. The non-registered user
+cannot use DX, ANN etc.
+
+The only exception to this is that a non-registered user can TALK or
+SEND messages to the sysop.
+
+=== 6^SET/STARTUP <call>^Create a user startup script
+=== 0^SET/STARTUP^Create your own startup script
+Create a startup script of DXSpider commands which will be executed
+everytime that you login into this node. You can only input the whole
+script afresh, it is not possible to 'edit' it. Inputting a new script is
+just like typing in a message using SEND. To finish inputting type: /EX
+on a newline, to abandon the script type: /ABORT.
+
+You may find the (curiously named) command BLANK useful to break
+up the output. If you simply want a blank line, it is easier to
+input one or more spaces and press the <return> key.
+
+See UNSET/STARTUP to remove a script.
+
+=== 6^UNSET/STARTUP <call>^Remove a user startup script
+=== 0^UNSET/STARTUP^Remove your own startup script
+You can remove your startup script with UNSET/STARTUP.
+
+=== 5^SET/SPIDER <call> [<call>..]^Make the callsign an DXSpider node
+Tell the system that the call(s) are to be treated as DXSpider node and
+fed new style DX Protocol rather normal user commands.
