Each person is a task. The attached note lists all of the things I need to talk with them about. One advantage to doing it this way is that I can e-mail someone the entire agenda. For instance, I have an agenda for our school system's tech coordinator. In the attached note, I have a running list of computer repair problems. I can print him a copy of the list or e-mail it.
The only time is let one item be a task all by itself is if was already a task and I simply changed the category. For instance, if I had an @Waiting For task that needed follow-up, and that follow-up was to talk with someone, I wuold change the name of the category to @Agenda and be sure the person's name was at the beginning of the task.
