Question - Posting to Forum's which are not yet available to students.

In my unit, Weeks 9 to 12 are set to be released in the future. The tutors would like to 'add a new discussion topic' in forums in each of these weeks, which are set up as 'standard forum for general use' with assigned groups. They would like to do this ahead of time so that the discussion topic/thread is there for students to contribute to at the beginning of each week.

Our only hesitation in doing this is that students could receive notification emails for forums that they are not yet able to contribute to, as these sections are closed, and this could cause confusion. Would this be the case? Or is it that because the sections are closed, they do not receive these emails.
