Mentioned above is the idea of chains, sets of transactions having the same subject and forming part of a continuing conversation. When you enter a new transaction into a DISCUSS meeting, you have the choice of starting a new chain or adding onto an existing chain. To start a new chain while in a meeting, press ``t'' for ``talk''; you may then enter the subject and body of your message. To reply to an already existing transaction, press ``r''; replying will complete the subject field for you by prepending ``Re:'' to the old subject. After pressing ``r'', the emacs window will split to display the current transaction in the upper half and to allow you to enter your reply in the bottom half.
After you enter the text of your transaction, which can be editted in normal emacs fashion, type ``Ctrl-c Ctrl-c'' (yes, twice) to send it to DISCUSS to be placed in the meeting. If instead you decide not to enter the transaction, typing ``Ctrl-c Ctrl-]'' (right bracket) will cancel your message without putting it in the meeting.
