ilan: Unfortunately, it is still possible to cheat on Cyberoro. Fairly regularly people refuse to end the scoring portion of the game by refusing to agree on dead groups. Since the clock is no longer running, this disagreement can last indefinitely. One can get an admin to adjudicate the game, but this is not so easy as the "call help" button doesn't seem to work and when in a game room it is not clear how to go to the main chat room to ask for help. So, in these situations, I have logged in on a second computer with another account and asked for help. This works well and the game is quickly adjudicated with excuses from admin and other users, e.g., "ah very rude player, sorry." This technique is also necessary for genuine disputes, e.g., the bent four in the corner pseudo seki, which, I discovered, was unkown to a dan player there.
mdm: you can click either on the button labeled "lobby" to go to the main chat. your game will remain active.
tapir: I don't share this experience. WBaduk usually miscounts teire, so one should play them out and force to connect. And end the game only on doing this. All disagreements during scoring I had were related to this fact, where players actually would agree but can't turn back (if undo is not available) to fill there and the client miscounts.
wentos?: I think that has beenfixed long time ago - not sure now but you can click (right click?) on empty intersection and it toggles its status (not counted is marked with red cross).
tapir: in my experience you can only change the status of whole areas not single points (where a stone to connect will be needed finally but isn't before the outside liberties are filled)
