Would it be feasible to have a section dedicated to Udemy courses that are free resources? Naturally no affiliate links, but sharing coupons / codes to get free access. I'm not meaning courses that people have ripped. Then is there a way to automatically lock a thread for replies say after 7 days. Reasoning here is some of the codes last days, some a matter of hours, but this would stop people bumping asking for new codes etc? Just an idea.
