Dave ,
Are you anoucing APL ToT  to more than just comp.lang.apl ?
I defininitely know my talk will also be of interest to  FORTH heads .
Here`s a list of  USENET groups I picked up some time ago , for whatever
use it may be :
 comp.lang.ada,comp.lang.apl,comp.lang.basic,comp.lang.c,comp.lang.fortran,
 comp.lang.perl.misc,comp.lang.pl1,comp.lang.rexx,comp.lang.pascal.misc
 ,comp.lang.smalltalk,comp.lang.forth

In a message dated 97-11-30 15:25:08 EST, you write:
> Are you anoucing APL ToT  to more than just comp.lang.apl ?
Not on usenet, except for comp.org.acm
> I defininitely know my talk will also be of interest to  FORTH heads .
Why don't you post an announcemetn to comp.lang.forth, mentioning your talk
and pointing to the web site: 
The appeal of your talk to forth users would not be apparent from our general
announcement. Feel free to copy all or part of our cxla announcement, or our
website info, for distribution where ever you think people would be
interested.

 I think that this is rather too broad -- most readers of most of these
groups would NOT be interested in TOT. Posting an identical announcement to
all of these would, IMHO constitute spam.

 Actually I got the list on a spam . /
 While I think you`re right about some of the groups , e.g.:  .basic  .pl1  ,
consider the ongoing  ' Re: Programming language vote - results '  thread
which is being posted to  ada , apl  , c , and c++  . /

Dave ,
 Sorry ` forgot to get back to you this morning .    /
My Bio :  -- gee , I have a lot of biographical material on http://CoSy.com ,
 but a couple of sentence summary ?
 Just say :

   the years , in business and personal life in New York and Chicago . He
   gives a big party every MidWinter which is this Wednesday , February 4 . /
