No clues at all? Just to gather everything I've found together:-
Note that all text files have one entry per line.
Add Theme
Use Game -> Add Theme
Uses three files Class.txt, System.txt and Rank.txt.
Each one should have a list of names with one name per line. They are loaded into the database to form the list of class names, system names and rank designations for the theme. The rank file should be in order highest rank to lowest, but this doesn't account for the new four sets of ranks? Now obsolete? There is an add ranks button on commanders but it may not work correctly?
Add Ship names
Use Game->add ship names.
This add ship names, not classes. Uses a ShipNames.txt file.
Add Names
No longer seems available, but used at a minimum three files called Surname.txt, FirstName.txt and FemaleFirstName.txt.
Add ranks works correctly. The ground ranks are a subset of the naval officers ranks. i don't have the game in front of me so I will update this post with which ones are used tonight.
Administrators and Scientists are known as administrator and scientist. I think you can rename them in game but each of them using just the one name with mulitple levels A1-A7(?) rather than ranks. Add names is a function that Steve can use. Worthwhile knowing if you wish to send Steve a naming theme to include. This is what I did for the Welsh name theme a while back (except I forgot to separate them into male and female first name files, Doh!).
