new category needed for chess package?

Hi, I've been working on a little side project for fun that is a combination of a PGN file manipulator, and a chessboard validator (sort of). The chessboard validator can be used to play a game of chess, since it sequentially validates each move. However, it also stores the game in a format that can be then converted to PGN using File_ChessPGN. The question is, where would such a chess package belong? It's not a validator, it's sort of a processor, but does not contain a chess engine that you could play against. Should it simply be in a new category called Games? Processing_Chess seems a bit odd to me, but is better than Science_Chess or Structures_Chess :). Any bright ideas? Greg
