I am rewriting an email assignment and I need a better subject. The book says the subject line should include a verb. The email is discussing the possibility of hiring interns. And some questions they should cover at their next management meeting, including date and time. I feel like the overall meeting they are saying isn't only about interns but interns will be discussed. Date is labeled as March 14th at 9:00 am.
