There is at least one site that has the map online, the site is called "The definitive guide to the WC universe" or sth like that, but I don't have the address. But I do have a copy of it on the hard-drive so if you don't find a site (which I doubt) I can email it to you.
I know the site mentioned by TC, but I'm looking for a more detailed map on the web (specifically Enigma sector and Vega) by detailed I mean by saying what is in that system (Like Agri-planet space dock whatever).
And I'll ask LOAF very nicely for some maps if I can't find 'em on the net.
We don't have maps that detailed... except in Gemini, and you'd have to take those from inside Privateer... Other than that, we have bits and pieces of information about what's in various systems, but it isn't compiled anywhere and it'd be a huge job to do it.
