A while ago, maybe FM 09 or 10, a guy named Chielini at the SI forums made one. I've been transferring it over from version to version, and trying to clean it up each time. Adding players, switching ages and reputations, etc. If there's anything you'd like to see or if I'm missing anything, let me know. Otherwise, there is no dedicated thread or anything.
I usually will add 15-20 players a week in addition to tinkering with other things to try to get them right. For instance, I cannot edit Bobby Charlton or Duncan Edwards. I mess around with them in the editor, save it, but then when starting a game nothing has changed. Still trying to figure that out.
