All Beta players are invited for a stress test event on the Lamannia server tonight from 8-11 PM EST. Testers who login during the event will automatically be entered to win a number of prizes, with the grand prize amounting to a free lifetime VIP subscription to Dungeons & Dragons Online: Eberron Unlimited.

Additional prizes up for grabs include three ATI HD4890 graphics cards, and 10 DDO Unlimited posters signed by the development team. Winners will be contacted via e-mail on September 14th, 2009. It also sounds like the longer you are online during the event, the better your chances are to win.
