Mail etiquette

[Phillip Susi <psusi@cfl.rr.com>]

You keep creating new threads with no subject when you reply.  This is 
rude and annoying.  When replying to a message you should be using your 
mail client's reply function, rather than start a new message and paste 
in your quotations.  This should preserve the subject line and add the 
proper In-Reply-To: header so that the message is properly sorted into 
the existing thread.  If you have been using your mail client's reply 
function instead of composing a new message, then your mail client is 
broken so please use another one.
