 <h1>Boost Discussion Policy</h1>
 <p>Email discussion is the tie that binds boost members together into a community.
 If the discussion is stimulating and effective, the community thrives. If
 the discussion degenerates into name calling and ill will, the community withers
 and dies.</p>

-<h2>Prohibited behavior</h2>
+<h2><a name="quoting"></a>Quoting and Message Size</h2>
+
+<p>Please <b>limit the amount of quoted text</b> in replies to this
+list.  Some people have to pay for, or wait for, each byte that they
+download from the list.  More importantly, it will save time and make
+your post more valuable when readers do not have to find out which
+exact part of a previous message you are responding to.
+
+<p>A common and very useful approach is to cite the small fractions of
+the message you are actually responding to and to put your response
+directly beneath each citation, with a blank line separating them for
+readability:
+
+<blockquote>
+<pre>
+
+&gt; Some part of a paragraph that you wish to reply to goes 
+&gt; here; there may be several lines.
+
+Your response to that part of the message goes here.  There may,
+of course, be several lines.
+
+&gt; The second part of the  paragraph that is relevant to your 
+&gt; reply goes here; agiain there may be several lines.
+
+Your response to the second part of the message goes here.
+...
+
+</pre>
+</blockquote>

+For more information about effective use of quotation in posts, see <a

+guide</a>.
+
+<p>A summary of the foregoing thread is only needed after a long
+discussion, especially when the topic is drifting or a result has been
+achieved in a discussion.  The mail system will do the tracking that
+is needed to enable mail readers to display message threads (and every
+decent mail reader supports that).
+
+<p>If you ever have to refer to single message earlier in a thread or
+in a different thread then you can use a URL to the <a
+href="mailing_lists.htm#archive">message archives</a>. tinyurl.com can
+help to keep those URLs short. Citing the relevant portion of a
+message you link to is often helpful (if the citation is small).
+
+<p>Don't forget, it's a single writer but there are many readers.
+So, saving some time for the readers is worth spending extra
+time when writing a message.
