Write about a career-related web site you enjoy visiting

If i have to provide a link of a website that I use frequently, that would U-cursos : http:www.u-cursos.cl.
In U-Cursos is all the information and material that I need for every subject I have, also some classmates writing classes in computer and uploaded in the page or I'm in a "group typing" in which I and some classmates we agree to attend certain classes and then write them into computer. Normally we send these classes by mail between classmates who are in the same group and sometimes we upload to "U-Cursos" for all other.
Sometimes, when I'm searching an information for a work, I looking for in a search engine like "google" a lot of the results just bringing to me to the home page U-cursos. I think this happens because U-cursos is a page that contains a lot of very good information.
U-cursos store a large quantity of documents, which are useful for all the different subjects that are in the career and allows us to see them, take them into our computers and downloaded from the internet.

And if it is a site that I like and that is related to the career I can indicate Wikiderecho which contains a lot of things like information about teachers who is about their lives, their occupations, their teaching methods, forms of evaluations, also contains some humor and another things; but the problem is that this website is managed by a political group of the University, which takes away credibility.
