Were you one of those people who turned the lights out and the power off for Earth Hour last month? Did you experience an excruciating sixty minutes of email/identi.ca/Facebook withdrawal? Userful has some good news (and a reward for your efforts) -- from now until Earth Day (April 22nd), it is giving away two-user licenses for its Userful Multiplier software.
So this time around, instead of turning the computer off, you can get the most out of its power consumption by sharing it with another user. While the Userful Multiplier software runs only on Linux, Userful is offering liveCDs bundled with the Multiplier software as part of this promotion, so those running other platforms can share the experience without making system changes.
