congrats, chacha-- it's true that your English is much better.
all you other tools who think it's OK to speak broken English, as long as you "know your material--" take note. chacha brushes up his English, and almost immediately, newbies like mcozire are calling him "level-headed," and practically begging to do business with him.
no one who actually speaks English gives a rat's *** about your engineering degree, if you can't arrange your prepositions correctly, and refuse to pluralize your nouns. these are instant red flags that you need to be treated like a fool, because you are "not from around here." sure, it sucks, but guess what-- it's like that.
so, slick, chacha. keep up the good work, and keep working on those articles. remember, first mention, "a;" second and subsequent mentions, "the."
