A lot of players type in GL at the beginning of each game. I play fairly quickly and start many games each day... so I don't always type in a greeting, although I feel bad if I don't. Yet greetings like GL seem so perfunctory... are these people really wishing me luck? (I should win more if the luck was effectual)
Anyway, I request that, in our settings, we can type in a default greeting. That greeting can be automatically shown on the first move of any new game.
