First of all, to those that may not have noticed for whatever reason, the rating center has been moved to the Battle Tower forum
. That forum used to be the Netbattle one, but has been changed to include Wi-Fi battling stuff as well. This includes things like organizing tournaments, discussion over your battles, and how the Wi-Fi battling world is shaping up in general. Discussion about Netbattle/Competitor stuff obviously still belongs there, too. The trading topic and the friend code topic are still here for the moment, and they will likely stay here.
We also have a Standard Movesets Guide that you can look at here
All topics that deal with that or the rating center will be moved to that forum and mostly without warning. Most (if not all) of the previous relative topics have already been moved.
