On the Edit Lineup page most of the column headings are self explanatory, but for newbies, like myself, who have never played above REC ball and want to try out a game for managing professional players, I suggest being able to click on the column heading and it give the name of the abbreviation (i.e. RF), which would give its meaning. Another suggestion would be a page (and every page in HBD) naming and giving a brief explanation of the column headings like you do for player stats and ratings. This would help to eliminate looking through thousands upon thousands of Forum pages to find the answer, unless of course this game is only aimed at college level or above players and MLB fanatics. At $25 a season I can see this is reasonable for those types of players, but I would think you would want lesser players as well, who would want to learn the aspects of the game and thus make it more competitive. I know you cannot explain every aspect of the game, but at least give some indication of what the abbreviation is so the right area of the game, forum or manual can be accessed. I would think your goal is to attract, teach, grow and most of all retain players of your game.
