whatupsmyaggin no it wont help others. Mega link survived 5 years, the links shared by you and those generated by the two sponsors wont.
Second, the links you requested are compressed, not segregated by courses. The moment one of the 300 links is irretrievable, a significant amount of data is gone.
Third, course content never changed. Yes, there are more courses, but like I said, you or no one will ever finish these courses.
Fourth, the contention here is that 300 GB is plain insane for one person to request and throttle all the bandwidth. Just because there are volunteers doesn’t mean you can’t exercise some self control.
