Ryan ChartrandThank you for the article Nov. 26 about our new class addressing design for impoverished communities, D-Lab. I wish to clarify the issue of eligibility. While we value the presence of advanced students and graduate students in the class, we are willing to consider freshmen and sophomores as well. We encourage all interested students to apply. The Web site describing our class is http://honors.calpoly.edu/courses/x491/index.htm.
