This contest has ended, but you can join our current contest.

Our challenge is to take your favorite content management system and make it better, solve a problem or add some functionality, using Nexmo's Verify or Number Insight. You could add second factor authentication to the login, build a gravatar-like comment system powered by phone numbers, keep user profiles and contact information up to date.

We all know the big names like WordPress, Joomla, Drupal - and you can certainly use one of these, but your submission can be for any platform that is open for extensions, integrations, or plugins. All submissions must be opensource and on github, because we want developers to see how useful these APIs are. 

Nexmo Verify makes it easy to verify phone numbers for second factor login, or for validating user provided data. Nexmo Number Insight provides data about a phone number - carriers, roaming status, and more.
