I see many online computer courses that sound interesting. I go to check them out and I see something Like "enroll for free", well thank you very much for collecting my info at no charge. But how about not wasting my time and first tell me how much the darn course will cost! By not telling me I assume it is expensive.
From Coursera website - Learn skills from top universities for free.
Then I read elsewhere "100 online courses from Coursera are $0 now through May 31"...so they're not normally free.
