multi-game challenges

it would be nice if there were more options when challenging players.

one example that'd i'd like to see is multi-game challenges.

when gms play each other, they often play a series of games (like 20). it'd be very cool to be able to challenge my friends to a series of games (2, 5, 10, etc). with each game starting immediately after the previous game has been decided.

then you could see the results in a table and the overall winner. obviously rating would be affected game by game, but the challenge of beating another player over 10 games would be fun ... especially if the games were connected and the overall result was visible (eg david vs friend (4-5-1) win-loss-draw)

i was going to suggest just making a tournament, but apparently you smallest tournament you can make is 4 players.

i thought of this too ... the other problem is that in tourneys, you only play an opponent twice anyway.
