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)
I have been "punished" with two losses, one in a tournament, because of rule changes or inconsistences. Why not restart the rating system again from the time of the latest rule changes and cancel all games which began before this date?
