For posting:
- invitations to games (you can also use the New Game menu)
- information about upcoming tournaments
- discussion of games (please limit this to completed games or discussion on how a game has arrived at a certain position ... speculation on who has an advantage or the benefits of potential moves is not permitted)
- links to interesting related sites (non-promotional)
Corporation: The games are there, they just do not appear to you in "Waiting Games" because you could not possibly accept the challenge otherwise you would be playing yourself.
Hope this solves your dilemma.
And to prove it, I have accepted one of your horde chess games.
