Hello,
You are joining us with lots of questions at the moment so why don't you register and join our community properly, so that we can get to know you a bit? It's free and you will not get any spam.
Also, these queries are better suited to the Vocabulary and Idioms section rather than Business English, so I have been moving them over for you. You ae more likely to get replies if you post them there in future.
