This is a new site that rewards residents with $Lindens for doing free surveys. You can also win $10 instantly if you first initial matches the letter of the day(see the bottom of the surveys page after visiting the site from SL!).
Give it a try and you will be surprised how quickly you can earn lindens!
You must visit from within second life to participate in the contest and surveys. This is to ensure reliable payment.
