Embarcadero Technologies is hosting an online challenge to perform common DBA/data modeler tasks in under a certain time frame.  If you complete the 4 challenges and are a resident of the eligible countries, you get the free t-shirt, too.

Embarcadero Technologies has thrown down the gauntlet to all database administrators, developers and data modelers. We firmly believe that our professional grade, cross-platform database tools, ER/Studio^®, DBArtisan^®, Rapid SQL^® and Embarcadero^® Change Manager^TM, can deliver measurable results in YOUR environment in less than 60 minutes.

For instance, the data model challenge is to reverse engineer a database and publish an HTML report in less than 7 minutes.  I know most of you could beat that time easily.

If you meet the challenges, I'd love to hear about your experience and your times.
