Preventing reply as linked topic


I must have done something wrong because in the student view they can still “reply as linked topic” to every topic - I thought I had prevented that, but maybe I am mis-remembering. The goal may be to prevent replying, not replying as linked topic, I guess.

e.g. here:

I want them to go to the week 8 discussion link on the right, not the “reply as linked topic” but they may get confused since both options are there so I guess I need to specify in the post itself. Liz was confused by this, too, when she reviewed the site (though unfortunately not from student view since I didn’t think of that) over the weekend.

And of course I don’t want them to reply to this topic at all, but I don’t think I can prevent that, can I?
