My company Barrel (www.barrelny.com) released a WP theme not too long ago that helps you create and track viral campaigns by assigning referral links to people who sign up. It’s called Launch Effect and you can learn more about it at http://www.launcheffectapp.com. We’ve had over 3,000 downloads in our first month, and hope you’ll give it a try for your next project. It works great as a “coming soon” landing page or a simple one-page website.
The theme is free and we’ve already released some major improvements since the initial version. We’d love your feedback on ways to make it better. Thanks!
