[Six String Guild]

I'm new to the game and trying to do something like what you want to do. From what I found out so far, you have to create a Fictional League, wipe out fictional players in the Draftee/FA pool. This gives you a blank league to work on. There is a way to one by one add a player in the game itself. If you use Baseball Reference.com, you can get the players ID and decide on the right year (whatever that is). It's tedious but that's all I've tried. There is the txt file import you could set up and do but I haven't tried that. That's probably the way to go since you'll always have a file to fall back on from the start but I'm guessing if you manually add the players, once done, you can export and save a file w/ those names and info on it. Good luck and let me know what you find out.
