I am reminded of the E petition organised here (England and Wales) which collected well over 100.000 signatures.

There may have been even more but the filters set up on the host site - meant that many more - simply because of their name or address - were just not able to sign. For example anybody trying to post with an address in Penistone in Yorkshire simply were automatically prevented from doing so...........As for those in Cockermouth or Upper-Dicker................

Every seemingly wonderful solution - usually also has a down side. Every wonderful invention of man - can also be screwed-up by man.
