OK, my first attempt at uploading those changelog things I was talking about. The first is a list of players whose birthdates were wrong. Most of the 20th century ones were off by just a year, so it was probably a transcription error. But to give you an idea as to how daunting this whole task is: it's over 500 players.

I could edit it and split into "slightly-off" and "way off" to make it more manageable, if need be. :/
And this is a list of players with the wrong birth nations listed. There were 12 players listed as being born in Toronto,
The United States, for example. (And I checked all the players, I didn't just assume it was wrong--there could be a Toronto, Kansas or something. I mean, there is an Ontario, California.)

So, yeah, just let me know if these work/are helpful, or if you can't open them, or whatever.
