The sample above for a discussion forum (made with Front Page and housed at a Front Page server at J. Sargeant Reynolds Community College) shows directions for students who use the forum, threading of comments under one question, and a range of dates indicating that at least some comments are left in the forum from semester to semester.  Feel free to write down the URL printed in the screenshot above to type into your browser; also, at this page, click on the directions link near the top of this page to read a copy of  the directions that students were given by email.
