There isn't a whole lot going on in the Pokémon Community at the moment... most people are just playing thier games. The Dream World feature which was supposed to open on March 30th has been delayed due to the recent events in Japan. It's still unclear when it will open up.
In the Organized Play front, big card tournaments are coming up, but there is still no word on when/where the Video Game Championships are being held. If your interested in when the card tournaments are being held, the dates are in the "Upcoming Events" list on the right. To find a location close to you, check Pokemon.com.
I have a couple articles I need to post myself relating to EV training in Unova, the Featured Pokémon for April, etc which I will try to get posted this week. I'm currently working on building a Double Battle team for this years VGC (whenever it may be) so I haven't got a chance to write them yet. Just keep checking back this week.
