Context is important (as it always is) but I have added above my opinions.Hi.
I have these questions that I encounter almost daily in my workplace.
When talking about the Lotus Notes calendar, do I use "on the calendar" or "in the calendar"?
I have no idea what a "Lotus Notes" calendar is, but generally we use "on the calendar" or "in the diary".
Is it "on behalf" or "in behalf"? I have never heard "in behalf". Always "on behalf (of)"
Is it "take him off the list" or "take him off of the list"? "Off of" is one of those very irritating habits that a lot of native speakers have. It's wrong. "Take him off the list" is fine.
Is it send to me or send me? "You have a letter. Send it to me" or "Send me the letter". Word order is important.
Is it forward to me or forward me? Same as previous answer. "Forward it to me" or "Forward me the email".
How do you answer the question "How's everything going?" Somebody told me that to answer "Good" is not appropriate as it is not the same as "How are you?"
There's nothing wrong with saying "Good". If you want to be precise, you would say "Everything is going well, thank you" but that is very formal. If someone is going to informally ask you "How's everything going?" you can say what you like in response. "Good", "Very well", "Fine", "Great", "Terrible" etc.
Thank you very much.
