Using gmail in the classroom

Using gmail in the classroom would be great for students in order to send group emails to their entire class list.  They could get constructive feedback from students and the teachers as well.  Students could also send critical questions regarding assignments, projects, and tests to the teacher that could be shared with other students as well.  That would be if the student sending the email felt comfortable doing that and decided to include everyone in the email.  It certainly would be a great way for teachers to get more organized with students assignments and tests as well.  Grades could also be posted in private for students to view as well.
