Before 1.7, you could select "No Discussions, but Replies are Allowed" when setting up a Forum. In other words, with this choice, only the instructor could start discussions, but the students could reply.
With the roles feature of 1.7, this is not possible. Or is it? How do you create "No Discussions, but Replies are Allowed" using the "roles" feature?
I couldn't find it at first, but here it is.
Select the forum you want to change settings for, then select the 'Update this Forum' button. There are two tabs, Update and Roles. Select the Roles tab.
Then select the Override Roles tab and select the Student role.
Select the Prevent radio button next to Start New Discussions to limit students to respond to the initial prompt message.
