I've recently picked up my copy of "Inside Microsoft Office SharePoint Server 2007", and just started reading it. There are not enough books out there in SharePoint and Microsoft Office SharePoint Server 2007 (MOSS), so its great to see a book like this, and even better that its such a good book. I've met the author, Patrick Tisseghem, a few times, and he's a great presenter and an excellent writer, so I can definitely recommend this one.
