BMF.io lets instructors know whenever someone buys their course. You'll get a quick heads-up, usually by email or right on your dashboard. It's super handy because you don't have to keep checking—BMF just tells you. It's also a nice little boost seeing new students sign up, kind of like a high-five from the internet. You can even use it as a chance to say hi or keep track of how your course is doing. The notifications aren't anything fancy, but they do the job and help you stay in the loop without any stress. Basically, BMF makes it easy to stay on top of things without making it a big deal.
