Is there a place I can report finds of systems with all the jumponium materials? Some centralized location?
Thanks.
There are several options:
You can use a tool like
EDDiscovery to upload scan results to
EDDB, where they are accessible by everyone, although this database does not list stuff like "systems with all the jumponium materials" (a.k.a. "Green Systems"), but if you know what these materials are you can search for them. I'm not sure if
Captain's Log also uploads to EDDB, neither am I sure of
ED Market Connector. One downside of these tools is that they can only send the data on the actual scanning event. You cannot send data that you have scanned already (EDDiscovery and Captain's Log can read your logs, so if the event is captured in the log... it might work).
You can also report your finds to the
Prospection Farm Locations for Engineers / Jumponium thread, and you can use this thread of course also to find some other farming locations. Especially Baronesse Galaxy has inspected quite some sites, not only for materials, but also for the scenery

.
Hope this helps,
