[Q]: Question: Possible Duplicate: "Toward" or "towards"? Which is the correct usage? "Onwards" or "Onward" ? For example: I would be free any time Tuesday onward. vs I would be free any time Tuesday onwards. Or is both correct/wrong? The spell checker in my browser says onwards is wrong but I've heard people using it. (p.s: Sorry if this question is redundant. I searched here but couldn't find a related question) 
Answer: Apparently, there is a slight difference, but only in British English: Note: In British English, 'onwards' is an adverb and 'onward' is an adjective. In American English and sometimes in formal British English, 'onward' may also be an adverb. So, depending on where you are, the difference maybe slight. However, they both mean the same thing practically, and most people will understand you if you use either anyways.
[A]: yes


[Q]: Question: What is the difference between "Did you find?" and "Have you found?" When should I use the first sentence, and when the second one? 
Answer: Did you find is the simple past and indicates that you are no longer looking for it. Have you found is the present perfect and indicates a link with the present, specifically, that you could still be looking for it.
[A]: yes


[Q]: Question: I am referring to someone who makes people 'buy' what he says and gets things done by them through nothing but clever speech something one can describe as crafty or beguiling, but not fraudulent. I pondered over con man and con artist for a while but those terms seem to hold a hint of crime, so those terms won't fit in. I am wondering if there is a more suitable phrase or word. 
Answer: Not quite a single word, but silver tongued probably fits.
[A]:
yes
