To find out what stairs you can currently challenge someone in, first go to the Main Stairs Page, then click on "Show your stairs only" link. The ones in BOLD are ones you can make a challenge in. .
I am playing a stairs game with someone who is not listed on the main stairs page. I do not know if they have left the stairs after starting a game or if they have started a retirement or if it is a bug?
Can we have a way to see who is on retirement and who has left the stairs all together please?
