Yeah I thought it might be nice to allow students to reply to Announcement but it was big mistake because everyone started getting email.
What I really want to happen, is for someone to post an Announcement, and then those who reply become subscribed to that Post. Which is essentially a Forum, however, the posts display in full and nicely on the Front Page.
For example, our Headmaster put out a Video called the Headmasters Challenge which appears very nicely on the Frontpage as an Announcement but students should then be able to reply to the Announcement. I dont want to set up a separate post for each announcement on the frontpage in a forum.
And I do want all students to be emailed the Announcement, but only students who reply should get emailed about replies to that post...
