I'm currently working for ICCK NET S.A., an online media company in Bogotá DC (Colombia). We have Drupal in multisite configuration for an important newspaper (www.elespectador.com), a TV channel (www.caracoltv.com) and 2 magazines (www.shock.com.co and www.cromos.com.co).
We want to use its features to the full potential, so I will be at the convention to learn everything I can.
