I thought the Lisp games community should know that someone on the Boston Lisp meeting contacted me privately in response to my post about the presentation I'm planning for later this year (see threads below). You may wish to be careful in discussing Lisp with people who are (or claim to be) former contractors for the US Department of Defense, and I urge you protect yourselves and to do your own research.
That is all for now.
