Does anyone know of a good site that explains vbscript or has some tutorials on vbscripting?

My other question for expert vbscripters is with using vbscript can I determine yesterdays date (previous days date) based on todays date (date on users machine)? I know that in vb to get today's date I use the word 'date' and it will provide me the date. Does vbscript work the same way?

Thanks for any sample code/advice in advance.
