I am not sure if this is where I should ask this question, but I am wondering if there is a specific place, on this site, where I can write my math notes on; using the same latex. I want to know because it looks a lot more clear to me to write notes on this site rather than on paper.
One option that doesn't require the hassle of a $\LaTeX$ package installation is the online editor at ScribTeX. You can write, save, and compile your code through the website.
I like using it for simple files like notes. An added advantage is that you can log in and work on your file from any computer.
