I am a player who usually plays a couple of games, then stop for a while and come back later.
That is why I only play games with 1 day per move.

My question is if anyone invites me, it can happen that I accidentally have a game that takes maybe a week or month per move.

It is a big question I have, because you have to reprogram a little bit, but I suggest that invitations you get you can adjust infront so you won`t be surprised by having games that can last forever.

ps. I don`t think this message would help, but is is an idea I had for brainking
Great site!!
