Points Per Credit: Number of points required for each credit. Each credit is equivalent to a survey response. Survey creator should have enough points to convert them into credits and can use each credit to invite a respondant. 1 credit is equivalent to 1 response, so if you put 10 point in this, each response require 10 points in survey creator account.
