In episode 49 of WordPress Weekly, I announced that the first person to give me the correct answer to the trivia question would win a free ticket to WordCamp Chicago. So far, no one has submitted an answer to the question. So with that said, if no one answers the question by the time the next episode airs, I will up the ante to two tickets. That is two tickets to WordCamp Chicago. These tickets were graciously donated to me to give away as prizes via Margaret Roach of Margaretroach.com Here is the trivia question:
What is the name of the software which is an enterprise edition based off of WordPress? Hint: stores all of its information in a set number of database tables meaning it has a normalized schema.
Update JLeuze has correctly identified the answer. Please see his comment here.
