Well a database of chess game can be just a .pgn file. A PGN file is really a textfile, to which you can just add new games by pasting the next one under the last game on the file (see below for an example of a pgn file with 4 games). This is an idea that you can use for now, before chess.com decides whether to add your feature or not.

I would like to be able to maintain a database of my own games on Chess.com.
I play over the board about once a week. When the games are over 15 minutes, I write them down. Then when I get home I usually put them into Fritz, both to analyze and so as to keep them in case I ever want to look at them again. But this is not ideal, mainly because I use several different computers, and Fritz is only installed on one of them.
If I could store them on Chess.com instead, I would be able to access them whichever computer I use, and indeed wherever I go. Also it would make it esasier to post them for discussion here.
I think it would be pretty easy to provide this feature, and I think anyone who plays over the board as well as online would appreciate it.
