Which invitations can I see on Waiting games page?
The Waiting games page shows you only the invitations you can accept. It means that this page never displays:
You own invitations you have created. Such invitations are included on Main Page at Your invitations waiting for response table.
Public invitations that you cannot accept. For example, if somebody creates an invitation with BKR > 1900 restriction and your BKR for this kind of game is 1764, this invitation will not be shown to you.
