how did you find this website? looks like some pretty cool models! I've been considering a cluster-staged model recently, wondering if there are any tricks - like venting the gap, etc.
anyways, net.trick: usually you can get an administrative email address from "whois" info about the domain. in this case it returns
$ whois advancedrocketry.com
