LATEX news group?

[Gill E. Fuchs]

Hello there,

Is one LATEX NEWS GROUP in existance?  If so, how would one get to it?
As i can't tell if one exists, i decided to post my question to the
UNIX news group.

  question:  how can one produce in latex a symbol that is used often
             in the AND THEREFORE part of a deductive logic argument?
             That symbol is a collection of 3 dots in a triangle (base
             on the bottom side) following a slash?  The 3 dots is the
             difficult part... :-)

             in an enlarged view it would look (somewhat) like so:

                     /  .
                    /  . .


much obliged for anyone who could help
