I think it's an oversight that the number of respondents per poll is the same (40) for both the k-12 free and premium accounts. What's the point of upgrading if I can't also increase the number of respondents? Sure, the size of 40 works well for a single class, but what about having an entire GRADE respond to the same poll at the same time to record accurate data? If the number of respondents increases for the Business & Non-profit plans (25, 50, 100, etc.), then why can't this increase also be applied to the K-12 plans? Upping the premium number to 100 allows for more application! This needs serious consideration.
