[44net] How do I work the gateways robot?

Hi folks, Is there a howto available that will tell me how to work the gateways robot? I am almost done working on the subnet breakdown for NJ (I'm the NJ co-ord) and will be needing to make some changes in order to put the plan into place. I'll be looking to add hosts to the DNS, change some existing hosts and change the master NJ subnet gateway (currently pointed at my house). I'm not proposing anything that hasn't already been done before. I'm simply chopping up the subnet into further subnets and allocating them to each of the counties with the "spare" numbers then being available for clever data experiments should there be any. Ordinarily I'd be doing this via the portal but ...... Thanks Mark G7LTT/NI2O
