Have no idea what a UseNet group is or how to find one? Visit www.remarq.com and search for forums that discuss "microsoft.public.scripting.vbscript". From there you should be able to find your way to the list of messages on the group.
When using resources for VBScript, keep in mind that most people use VBScript for developing dynamic web content. Therefore a lot of the discussion may be geared towards embedding VBScript in web pages.
