I have an idea about LittleGolem rankings, what about place a small coloured square in front of the points?
For example, -1500: green square1500-1699: blue square1700-1899: yellow square1900-2099: orange square2100-2299: red square2300-2499: violet square2500+: white square
An other topic about connexion, it should be good if we can see if the opponent is online, so just put an other kind of figure behind the account to show that the player is online can be good.
How about some indication how long it has been since they have been playing. It appears that some people on the rankings have not played a game in years.
