[Simetrical]

For an accurate survey, only a random cross-section of the readership should be allowed to take it. That is, I would like every (say) 1000th hit to be asked to take the survey, guest or no, but no one else should be allowed. (If someone would be offered it twice, I suppose their answers should just be doubly weighted, or they should be skipped, or it should just ask them to take it again.) Is this reasonably possible with this hack? From what I seem to be reading, it's just a page that members can express their opinions on, but I have a pretty good line to the members through the forums themselves. I really want to hear from the anonymous viewers.
