Hi! How do you know if a certain person is online? For example, if I search a certain person and look at their profile and games, how can I tell if they are currently online or not?
Be excellent toward them and ask if you may add them to your friendlist.
Go to their profile (or on the “available games to play” page) and click on their name. In the pop-up that appears click on Message and in the box that appears check the upper left corner: if there is a green ball there, then they are currently logged into the site.
