After briefly climbing to 4k? on KGS, I finally solidified my rank on the server and settled in at 6k with no question mark.
I should be able to keep the question mark from coming back if I continue with my program of playing five rated games per week.
Today I put up my offer in Wings, then Go Discussion, and finally the English Room before finally getting a taker. It took over a half an hour before I finally got a game. I played a 6k today, and lost, to stabilize my rank at 6k.
