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 think you might need to reread the rules. Basically, when you or an opponent takes a piece all the pieces on adjacent squares (except pawns) belonging to both sides are also taken in the "atomic" explosion. Awesome really!
