I registered beforehand and have done four daily entries on the page the scopemonth URL redirects to. I still haven't received an email.
What is more, I put 'UK' each time and on one occasion got a list of UK distributors to choose my 'preferred' one from (I chose Radiospares), but on the other 3 occasions I only got US distributors. So not everything is working properly.
I too am concerned that it would be too easy to write a script to do multiple entries, with random email addresses on one of my domains. I suspect that bot writers will get 10,000 entries for each genuine engineer's one. They may have to go back to drawing from an early day's entry if the number of entrants rises exponentially to exceed the number of humans on earth.
However, Keysight is doing the giving, so it's their call!
