-<P>It is possible to isolate networks from each other on a "gateway" node using the
-<EM>set/isolate <node_call></EM> command.
-<P>
-<P>The effect of this is to partition an isolated network completely from another
-nodes connected to your node. Your node will appear on and otherwise behave
-normally on every network to which you are connected, but data from an isolated
-network will not cross onto any other network or vice versa. However all the
-spot, announce and WWV traffic and personal messages will still be handled
-locally (because you are a real node on all connected networks), that is locally
-connected users will appear on all networks and will be able to access and
-receive information from all networks transparently. All routed messages will
-be sent as normal, so if a user on one network knows that you are a gateway for
-another network, he can still still send a talk/announce etc message via your
-node and it will be routed across.
-<P>
-<P>The only limitation currently is that non-private messages cannot be passed down
-isolated links regardless of whether they are generated locally. This will change
-when the bulletin routing facility is added.
-<P>
-<P>If you use isolate on a node connection you will continue to receive all information from the isolated partner, however you will not pass any information back to the isolated node. There are times when you would like to forward only spots across a link (maybe during a contest for example). To do this, isolate the node in the normal way and put in a filter in the /spider/filter/spots directory to override the isolate. This filter can be very simple and consists of just one line ....
+<P>As usual, any text behind a # is treated as a comment and not read. To use
+this file, simply rename it from startup.issue to startup. In our example
+above there are three options. The first option is the amount of spots that
+a user can request with the <EM>sh/dx</EM> command. Normally the default is
+to give 10 spots unless the user specifies more. Without this line enabled,
+the maximum a user can request is 100 spots. Depending on your link quality
+you may wish to enable more or less by specifying the number.</P>
+
+<P>The other 2 options are dealt with more fully in the security section.</P>
+
+<P>Secondly, it is used to store the login scripts for users and nodes. Currently
+this can only be done by the sysop but it is envisaged that eventually users will
+be able to set their own. An example is included in the distibution but here is
+a further example.</P>
