The blue used in this website gives it a casual look and undermines the seriousness of the website as a learning site. It appears to be more for social engagements. Using black for names and a strong font will be nice.
Also, can I suggest comparing with other sites like Alison. I use my phone to access this site and maybe that's why I can't see my dashboard. I have attached some pictures of my dashboard on Alison to further explain.
