Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
mctrivia: PGN is human-readable, so one way to use it is simply to open the file in any text editor: you'll find some information identifying the game and a list of the moves in Standard Algebraic Notation. Also, most chess programs (e.g. XBoard/WinBoard) will let you view and save games as PGN.
I'm also in favor of Matarilevich's suggestion, especially since the PGN format allows one to store many games in a single file. Perhaps it would also be nice to be able to download all the games from a particular tournament at once.
While we're on the topic of PGN, I'd like to repeat my request that the PGN files for chess variants identify the variant being played by using the "Variant" tag (and in the case of games with different starting positions, the "SetUp" and "FEN" tags).
