I do the same as you Julian but becuase I code I don't use illustrator or anything - I simply descript to the client what each file will basically do and if they need to know what a function does I will tell them.. Sometimes it actaully helps when the client knows something not just for eample 'I want a sotw script'. They should always give more advanced details for example 'I want a sotw script that users can submit sigs and the registered users intergrated with vB can vote on'. Then I will ask for a document with specifics and before I get started or request a deposit I will type up a pdf document or something with all the details on..
