Difference between (Reply to Group) and Reply?
Reply to Group means that you are replying to the newsgroup/classroom. Reply means that you are replying to the person who posted the message, not to the entire newsgroup. If you reply to a posting using Reply, you will not see that post in the newsgroup but the person who you replied to will see it in their UIU email box. This option should be used if you want to personally reply to the post and do not want everyone else to see the reply. Most instructors do not want you to use this feature.
