This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
This is a normal thing -- in fact, I have yet to find a person that has been able to upload their assignment the first time they have tried! Consider it some extra time to exercise some deep-breathing and look at your assignment objectively one last time.
