Turbine is hosting a beta stress test for Dungeons & Dragons Online: Eberron Unlimited tonight at 8 p.m. EDT on the Lamannia server, and you can win some big prizes simply by logging in and participating in the event.

All players who log in between 8-11 p.m. tonight will be entered to win the grand prize of a free lifetime VIP membership to DDO Unlimited. Three first prizes include ATI Radeon HD 4890 cards, and 10 other beta testers will receive signed posters.

DDO Unlimited was actually supposed to go live for all players today, but the launch was recently pushed back to Sept. 9.
