If only First Opinions is still accepting new members. Anyway, they released a new survey that pays 500L$ which quotes "This is an interesting project for a graudate student working with his faculty committee."
So for the members, don't forget to take the survey for an instant 500L$ free lindens.
For the non-members, let's just wish that FOP will open its doors to new members again. This is highly possible though for the fact that most of the old FOP members are either busy already with their First Life or doing something else in the Second Life.
