In that case, CoderCharts would be helpful since for beginners, they don't necessary have to take part in competition. We have non-contest puzzles of various levels for users to try their skills. We have plans to push out more social features to enhance the users' sense of pride in their skills, so this would help nurture freshmen's interest. I would encourage you come to our site and play around yourself, so that you have a better understanding of how to make the most out of it. :-)
