Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
playBunny: I have also never turned down a game request by anyone with the "rating window" where I don't have to lay 14-1 without good reason and offering a counter proposal (usually a longer time limit). I have also, on occasion, accepted a game from someone 400 points below me.
I do play for rating. It's part of the competition on here. I will say ELO ratings are not a good fit for BG, but that's the way things are on here. I know different systems are out there, but I don't know enough about them to reccomend one.
On the feature request side, it would be nice if we could wager Brains one here. Not sure about the legality of that in the Czech Republic, and everywhere else for that matter, but it is worth a thought or two. I know I've mentioned it before. I'm not agitating, just thought it would be a good thing to bring up given the context.
