This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
Beats me! But I have a call into the publisher and hopefully she can get hold of them soon. But even if the authors don't show up we will still be giving away the books so keep asking (and answering) those questions.
