May have stumbled upon something...

I have this idea for a website called Cheatsheet.com....It would basically be a website that has A. Has cheat sheets for certain topics. Would be good for languages and math possibly. This would have them in cheat sheet format. And B. You could also put in what you want and it would make the perfect cheat sheet. I have not checked if this exist but if it does that would A. SUCK because I wont possibly be rich and B. Be awesome because I really won't have to study for my test tomorrow. (Which is the reason I thought of this website)
