This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I've got a working application, and it seems to meet the requirements. However, before I submit my project, perhaps some could share any ideas on final QA processes, or things to look for / check for before submitting the final project.
