Steven Feuerstein's PL/SQL Challenge

If you have not already seen this then take a look at Steven's latest initiative: "The PL/SQL Challenge " http://plsqlchallenge.com The Challenge was launched on the 1st April and so you can get involved right now. The Challenge should do a number of things, you might "meet" some new PL/SQL whizz-kids or indeed find you are greatly proficient yourself, I'm certain you'll learn stuff and have some fun while you're at it.

As Steven says
"The Challenge is free and simple: you play the quiz each weekday. We keep score. You get ranked. Every three months, the top-ranking players compete in a quarterly championship to award first, second and third prizes. Cash prizes, among others. But that's not all. Every month, we will raffle off other prizes to anyone who played the quiz that month. And the more you play, the greater your chance of winning. "

The site looks great and is easy to get around, you should be able to nip in each day and play. Take a look at the rules too, it all looks like good fun. What's more you'll probably learn bits too, with the Oracle database, rules change over the years, some of the questions and answers may well have you delving into an area you are unfamiliar with or even scratching your head with "I didn't realize that was true". Nice.
