On July 29, hundreds of bloggers from around the world will put their endurance to the test for charity, blogging every 30 minutes for 24 hours straight. This is the Sixth Annual International Blogathon, an event that creates a worldwide community for a day, serves up fascinating content, and most importantly, raises tens of thousands of dollars for dozens of charities. Bloggers choose the charity and collect sponsorships. At the end of the event, those sponsors fulfill their pledges directly with the charity.

It’s not too late to sign up if you’d like to blog! You can also help by sponsoring a blogger, just check out the List of Bloggers at the site. Stay up late, make a difference.
