You can click on this image, go to Innocentive , register yourself and start solving a problem.
The best part I like about the program is that it doesn't restrict you to a specific field. There are some good programs similar to these but they are very restrictive. Like astronomy, some linear *** coherence *** something (I don't even recollect the name :P). There are many of us with diverse backgrounds and we generally tend to look at challenges in our fields.
This is one such site where people with diverse interests can pay an attention to.
Most of the people solving the problems here are Phds. No matter what, attempting it far better than not giving a try.
The fields for which they have open challenges are
Business and Entrepreneurship
Computer Science and IT
Engineering and Design
Mathematics and Statistics
Requests for Partners/Suppliers
That obviously appears to be a very huge list. From what I see, they have at least covered many major areas. If they still expand it further, it would be one of the best places on the internet for challenge lovers.
