Have you ever wanted to contribute to Wolfram|Alpha? Yo can do now, Wolfram|Alpha made it easier than ever to contribute with "Volunteer Central," the new landing pad for Wolfram|Alpha volunteers. "Volunteer Central is a place for contributors to get updates, check out new projects, and track their progress. Projects are categorized into challenge areas, which're searchable in the dashboard. After creating a account, you can easily find projects to work on, upload them, and see your completed and in-progress projects all in one place.
Uploading a new project earns you "data points", which add up in your dashboard. Different levels of data points will earn you badges that you can display proudly on your Facebook page and Twitter, as well as other websites," explained Wolfram.
