You can now, at least for a brief time, sign up for the Guild Wars 2 beta. It would be a good idea to do so. Word and video out of the press beta held last weekend has not changed my opinion that GW2 is the most exciting looking major MMO on the table for this year. There are some obvious problems that will hopefully get fixed before the launch, though.
Also, SOE is offering double Station Cash on redeemed points cards this weekend, but only the cards sold by GameStop. If that’s where you’d ordinarily get your cards anyway, it’d be a good time to add some points to your account.
