More downloads I missed from my last post:

• Visual Studio 2005 Extensions for WSS 3.0 (Nov CTP)
  • Tools for developing custom SharePoint applications: Visual Studio project templates for Web Parts, site definitions, and list definitions; and a stand-alone utility program, the SharePoint Solution Generator. (I have yet to download and install this but the SharePoint Solution Generator sounds like it could put me out of a job!)
• SQL Server 2005 Data Mining Add-ins for Office 2007 (Nov CTP)
  • Two add-ins for Microsoft Office Excel 2007 (Table Analysis Tools and Data Mining Client) and one add-in for Microsoft Office Visio 2007 (Data Mining Templates). [Thanks to JamieMac]
