Here’s the official announcement (taken from the ODTUG page):
ODTUG is holding its first ever world wide APEX Plug-ins competition! This is your opportunity to write an APEX plug-in and have it viewed by the entire international APEX community and maybe crowned 2012 ODTUG APEX Plug-in Developer of the Year! Even better, there are some really great prizes with the grand prize being a free pass to Kscope13 or a Jawbone Jambox!
This is an opportunity for you to not only win some cool prizes but also to show just what is possible with APEX plugins (and don’t worry if you’re a beginner in APEX, there is a separate Experts category to make sure that everyone is judged as equally as possible).
