Update: SharePoint 2007 Resource Guide
Just updated the original SharePoint 2007 Resource Guide I published in Jan 09.
You can download the updated guide here - MOSS_2007_Resource_Guide.pdf and access the Online version here - Microsoft Office SharePoint Server (MOSS) 2007 Resource Guide.
SharePoint 2010 is almost there, so might not update the guide anymore. Thanks for all those who downloaded the guide and provide me valuable feedback.
