3.1.7 Facilitating forums

When you reply to a Discussion forum message, you have the option to simply maintain the default subject line for your message, which will be "Re:<message subject>, or compose a new subject line. In a discussion topic with many replies, the subject lines can quickly become meaningless, since the ideas presented may diverge quite a bit from the original topic. 

Remembering the many participants will be subscribed to the forums and receive messages via email, having a more descriptive subject line can help comprehension quite a bit. 

To change the subject line, simply edit the default Subject field in your reply. It is very simple capability, but often forgotten.
