You’ve probably seen their videos on the YouTube popular page. You’ve probably heard chatter about some No. 1 New York Times Bestselling author from Indianapolis. You’ve probably read one of his books, or one of your friends has probably tried to get you to read one.

Project for Awesome 2013 made its launch yesterday at noon, led by brothers John and Hank Green.

John, author of the book-turned-movie The Fault in Our Stars, and his brother, Hank, who is an environmentalist and who organizes VidCon annually, will be broadcasting via webcam for a couple of days through a Google+ live stream.

The live stream is only possible because of the time, talent, and money YouTubers and the YouTube community give. A few of the contributors this year include Craig Benzine, Michael Buckley, George Watsky, Josh Sundquist, Olga Kay, Sarah Urist Green and Charles Trippy.

The project has taken place in December every year since 2007. Last year, the event raised $483,296 to be split across the top 10 selected charities and 724,167 comments were left by viewers. As of the time this article was posted, $433,933 had been raised towards non-profit organizations and 258,189 had been left by viewers.

Donations to the Foundation to Decrease World Suck (which is a real entity – the IRS even says so) are encouraged with “perks” – items of varying cost that those who donate will receive. Perks range from a $15 commemorative coin to a $300 voicemail on your phone from John Green reminding everyone who calls you to not forget to be awesome.

Whether or not you make a monetary donation, you can still go to projectforawesome.com and find and vote on a video for a charity you believe best deserves the funds raised. Videos submissions have been made promoting charities across all categories like animals, education, environment, health, hunger, poverty, the arts and water.

Currently, some of the most popular charities are Deworm the World, Liberty in North Korea, Doctors Without Borders and This Star Won’t Go Out.

You can also help out by commenting on the videos on the website; each comment counts for a penny towards the fund.

The live stream ends today (December 18), but donations will still be taken for four days towards the charities.
