Essentially, I have created an account using only underscores, no regular letters or numbers. My account is ___ (3 underscores) http://online-go.com/user/view/86659 . I have played around 10 games since creating the account, 5 of which are definitely known to the system as they were ranked games, all of which I lost (Elo rating was also affected), as you can see in my profile. However, the other 5 games - or however many I have played, are not tracked at all, on either mine or my opponents profile pages.
I’m not sure if this is an indexing problem, like others have been having - but I am making a separate forum thread regardless.
