Recently PlayOnline opened their website where users can sign in for beta testing on the Xbox 360. A Xbox Live account is required to register. Players from Japan, North America and Europe can participate.
In the beta version some features will not be available, like font and characters specific for the European region, USB peripherals (excluding the USB keyboard and mouse) and wireless LAN adapter compatibility.
Xbox 360 players will play on a stand-alone server during the beta, so not with PC and PS2 players. After the beta players will join the PC and PS2 players.
So, if you wanna participate in the beta test, get the February issue of Official Xbox Magazine which will be released on January 17th.
