- 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)

Pythagoras: Sorry I misread you ! I thought that you disagreed with my promotion rule because I missed the "only" in your first sentence. A more careful reading switched the meaning of your sentence completely :-)
