To build your DMA, first enter the name of the primary city. This is usually the most populated city, such as: New Orleans, Dallas, Atlanta, etc...

Then press the "Add City" button to add a new city to the DMA. In the field that appears, add highly populated suburb cities. For instance, in New Orleans, these would include Metairie, Kenner, Covington, etc. DMA's can contain at most 10 cities/suburbs, including the primary city. We suggest you use Twellow to help you find the most suburb cities with the largest twitter populations.

Once a DMA is defined it can not be altered. With that in mind, please try to be as comprehensive as possible and include the top 10 cities in the area because your definition of the city will become the official city in our list.

When you are finished hit the "Complete" button to see the results. And thanks for helping us to build what we believe to be the first DMA level local twitter directory.
