First off, has anyone here heard of this project? I just stumbled upon this and it looks quite fantastic. It's called compilr and it is an online IDE for many languages, including C++! It has a really clean look and feel to it, and most of the functions are there. As of now, it doesn't let you compile and run your programs yet, but the admin, tim.speed says it will be up near the end of this month. This project looks really promising, it's packed with so many features it's not even funny. Check it out -
