My girlfriend recently spent a month in Toronto and New York. We live on the West Coast, and when she left I got her to start a BK account so that we could play and chat while she was gone. (Her name on BK is ultramarine.) We made moves on a couple of games from across the country, but now that she is back I was concerned that we would both be playing from the same IP address and that one day someone at BK would think that both were the same person. After our current game of go 13X13 is finished, I decided that from now on we should only play unrated, uncounted games with each other online.
I suggest that couples and families who play on BK from the same IP address somehow register as multi-party users and then BK admin could have something set up so that all multi-users from the same IP addresses default to unrated, uncounted games. Such a preventative measure would limit the chance of cheating on this site, and that is something that has been addressed before on brainrook.com as well as on these discussion boards.
