You know, there are a lot of things that could use a little (or maybe a lot of) Nexmo. It could be an opensource project that needs some SMS support, or 2FA security. Maybe it's a service with plugin support that could use some phone number insight, or the ubiquity of a phone call.

We're looking for some Nexmo powered feature or functionality to be added to an existing project, server, etc. Not a wrapper library for a language or framework. Something like adding an SMS gateway for Slack. Not a fan of Slack? (Really?) Then maybe an SMS gateway for the Mattermost project

You could turn a Mailchimp list into a voice broadcast system. Perhaps enable a Google Form to accept responses via SMS or IVR. Or maybe add native call tracking to Piwik's analytics dashboard.

Whatever it is, this contest is your chance to add Nexmo - and when you win, we'll add some prizes to you!

You can add Nexmo to anything. Your submission shouldn't work on it's own, so be sure to include details on how and why you added a Nexmo powered feature to that exsisting system, project, service, tool, whatever. 

Want some extra credit for hacking? Post your Nexmo API key (not secret) in this thread to have some added.

So what are you waiting for? There are some links below to help you get started, hit the 'register' button on the sidebar and get hacking!
