Hi Folks, Another email arrived from Helen Harris and I realised I need to find a "home" for these sort of snippets. Consequently there is another new web page - Research Bits and Pieces. http://zades.com.au/gandd/index.php/geelong/research/gdresbits As you can see, there is scope for adding all sorts of "bits and pieces"! Just email me. Regards ................ Susie Z
