If I pull up the "Assignment" tab, I can see 17 discussion boards. Half of them have a page with an "A" on it as their icon and the other half have a "talk bubble." When I call up "Discussions," only the assignments with the "talk bubble" show up. They're all accessible through "Assignments," but I'm concerned that my students might not see the ones that aren't showing up under "Discussions." Is there a way to convert them from a generic assignment to a discussion?
