As someone who is extremely interested in getting started in the e-learning space, what are some ways to offer credentials to people via your e-learning company? I imagine there is a host of options, ranging from formal university credits (which would require teaming up with some educational institution) to just an email saying "congrats, you done it bro". I'd imagine the interesting options lie somewhere in the middle?
