Can you afford, and are you willing to pay, my private consultation fee?

Yes, Joe I use that one when the second e-mail arrives> the first e-mail, usually do not state "term paper" and, as such, I refer it to the forum.

Often after 'first refusal' a second e-mail arrives, "I have to turn in my final paper next Thursday, I am desperate, please send code and schematics".

I have been tempted to send a schematic with strategically placed components that will blow up with a big bang when power is applied, but since no one has continued after e-mail #2 I have not done so (yet). Of course, if, indeed, the issue was a term paper, and the response were "where do I send the check" there would be only one such component. If the request was for an industrial application, my usual consultant practices (good solid working design) would, of course, apply.
