You lot are getting real cynical...he may just be trying to better himself...and get out of that Delight factory,where the merest discrepancy in chocolate thickness,earns you fifty lashes...
Many people want to better themselves, the question is, how to do so effectively.
Its a competitive world, and if people's responses aren't what the op hoped for then their next step in 'bettering themselves' is to come back with an improved question. Or accept the fact they didn't try as hard to seek knowledge as someone else might.
Its an electricians forum, we all know laziness equals danger in the real world... Its actually disrespectful for the op to expect anything from such a lazy question.
Hence, I doubt we will hear anymore from them. Although I remain hopeful we will, and in a somewhat more structured manner. I personally feel it's very rude to put less thought into a question than you expect others to put into answering it, that's my bugbear..
