Hi,
I'd like to see a clear outline of the rating change per game: eg
W (1234) vs B (1300)
Win 1240 1280
Draw 1238 1290
Lose 1233 1270
Maybe this could be in the form of a rating calculator, and per game just list the start / finish ratings of each player. I like to know what my rating was at the beginning and how the game affected it - although this will never make it a better player it's still interesting!
