Slashdot rejected Paul's post (appended below).  Oh, well.  Get the word
out in whatever way you can.  (Blogs, whatever?)  Feel free to just use
this text, if you wish.  Or not.

<a href="http://www.cs.berkeley.edu/~nikitab/">Nikita Borisov</a> and 
<a href="http://www.isaac.cs.berkeley.edu/~iang/">Ian Goldberg</a>
have released
<a href="http://www.xelerance.com/mirror/otr/">Off-the-Record Messaging</a>,
an IM plugin for private communication providing not only
the usual encryption and authentication, but also deniability and
perfect forward secrecy.  Deniability avoids digital signatures on
messages (while preserving authenticity and integrity), so there is no
hard-to-deny proof you wrote anything in particular; in fact, there is a
toolkit to help people forge messages, making it extra-hard to pin
things on you.  Perfect forward secrecy means that your past messages
and conversations remain protected even if your keys are compromised.

You can read the
<a href="http://www.xelerance.com/mirror/otr/Protocol.txt">OTR
protocol description</a>, download the
<a href="http://www.xelerance.com/mirror/otr/gaim-otr-1.0.0.tar.gz">source
code</a> for the gaim-otr plugin, or grab a gaim-otr binary package for
<a
href="http://www.xelerance.com/mirror/otr/gaim-otr_1.0.0-1_i386.deb">Debian</a>
or <a
