Visit the retired Google SketchUp Help Group. The Groups were retired in 2009 after the new Google Help forums opened. like SketchUp General, Using SketchUp, SketchUp Issues, SketchUp Pro, LayOut, Style Builder and Feature suggestions. (the SketchUp Pro, LayOut, and Style Builder Discussions contains material dating back to the original, @last General forums,)
Once upon a time, pre-Google, SketchUp ran its forum on another platform. When the Free and Pro forums merged on Google Groups, some of the sub-forums were retired. The old material from the original SketchUp Pro forum still has useful content found in SketchUp How-To, Deutschsprachiges Anwendergroup, Ruby API, GIS and SketchUp, SketchUp and Materials/Comonents/Styles and Gallery.
