PGN games
I would like to suggest you one idea. I know that I have my last games available and if I am VIP member there are a lots of it... but until I cant work with them like with database, they are useless. I think lot off players would appreciate to work with their database, when they are studying some openings and look for the most often answers to their moves. Fore example some sites saves your games directly into your chessbase software.
Thanks
