\label{Course_Disable_Discussion}
By default, all users of a course can use the discussion features
LON-CAPA provides. Only Course Coordinators have permission to disable
discussion for a course. A Course Coordinator can also disallow
resource discussion for specific roles or specific users.

To disable discussion, do the following: 

\begin{enumerate}
\item Select \textbf{PARM} on the Remote Control or Main Menu.
\item At the \textbf{Set Course Parameters} screen, click the \fbox{Set Course Environment} button.
\item Scroll down to \textbf{Disallow Resource Discussion for Roles}
  or \textbf{Disallow Discussion for User}.
\item To disallow resource discussion for specific roles, enter a
comma-separated list of roles, for example: \texttt{st, ts}. This will
disable course discussion for the specified roles. To disallow
discussion for a specific user, enter \texttt{username:domain}. 
\item Check the \textbf{Set} field if not checked.
\item Click the \fbox{Set Course Environment} button.
\end{enumerate}

NOTE: Your changes will be visible the next time you log in, or by clicking the \fbox{re-initializing course} button on the \textbf{Course Documents} screen, whichever comes first.
