Hi and welcome here,
this forum say all about the game, and you can ask questions.
And for the tournaments, you can see here:
forum23.php1 tried to help you, and I wish you understood.
Read the rules there, and try to come often in this forum to see if there are new tournaments, the draw is released on sundays, you have the sign up for tournaments in the Tournament Site. On each round you have one deadline means the last day to play your match, if your opponent didn't show up before the deadline, contact one mods (tournaments) add them on MSN, then you will get a Walkover, but if you don't show up before the deadline he will got a Walkover, if you played your match you should report the result in the official topic of the tournament, well it's all I have to say for the moment, I wish I helped you more, if you have any questions we are here for you.
