           ficult to get people involved because
           someone who is volunteering for

           more of the research is private.
            Q: What are your goals for the fu-

            A: Today we have about 100 mem-
           bers. We have to keep it on track. We
           are  now  involved  in  both  wire  and
           fiber rope. For the 2017 conference,
           more  than  30%  of  the  papers  were
           related to fiber ropes.

            A: We just modified our website to
           make all the research papers acces-
           sible to our members. We’ve spent a
           lot of time doing that, but it’s more
           or less a moral obligation. I hope
           this  will  be  finished  by  the  end  of
           the  year.  We  have about 700 pub-
