Thanks. I needed that information from a very long time. Solved my several ambiguous problems regarding to these little words and their usage.

I'm not sure what you're referring to here. The OP was rather poorly formatted, so 5jj tidied it up so that it was readable. So far, no-one has actually dealt with the question so can you explain how the posts have helped you to solve problems you have had for a very long time?
