This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
The forum software does not include a preview feature, but, if the post doesn't come at as you wanted (which seems to happen to me about half the time!), you can edit your own post to modify it to suit your intentions.
