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.
Under sequence diagrams, how do we draw return arrows (that return value back to caller)?

Instead it creates a new timebox which probably means calling a method on caller (not my intention).
