In case you need online courses you simply google them directly, right ? So I assembled a simple search tool that looks specifically at MOOCs - you know, Massive Open Online Courses. Permanently placed in the right column of the Brînzoaice cu gem blog.
More exactly, the search tool is targeting the subdomains containing the course lists of (for the moment) Coursera, iversity, edX, Udacity, FutureLearn.
Search wisely :)
