This year for the first time we include the main contact email for each exhibitor to make it more helpful for an attendee to contact an Exhibitor.   But this was a mistake as numerous scam artists are contacting our Exhibitors trying to sell them a list of attendees.  Because of this activity we have now removed  (8-12-21) the email address from the Exhibitor Directory listing on this WITS Website.   If an Exhibitor  wants a list of the 2019 attendees just contact the WITS office and we will provide it, free of charge.
