As of this time, JumpJet has ceased Serving via the Gopher protocol. Network News protocol service has also been terminated, but the HTTP protocol service remains. Please update your Gopher sites to remove pointers to the old JumpJet Gopher Server.
Note that the "Begin Here" selector is now being hosted on HAL3000. This is an excellent Gopher resource for both New and experienced users, and worthy of a Gopher link.
