Guys, I have not seen a poll where you need to input your email address - and if I would I would not vote - because it's a waste of my time... if you want me to vote you do everything you can to make it as pleasant as possible -- certainly that isn't requirement of an email validation.

You're missing my point. Yes, e-mail addresses are unique delivery

No -- I did not miss you point, your point is obvious.

I simply said that if it were me, this is what I would do. I also added that
my method ensures one vote per email address. I did not say that an email
address ensures one person.

I am sure we both agree.



It all depends on the domain of the problem in which one is working.

I agree that you could restrict it to one vote per e-mail address.
Obviously, I can't speak for the OP. I've worked with applications
where e-mail addresses were limited to a single domain and every user
had one, and in those cases the e-mail address made an excellent key.
I have also worked in situations where the correlation between people
and e-mail addresses was n:m rather than 1:1 or even 1:m. In those
cases, the e-mail address was totally unusable as any kind of key.

Then there is a broader scope where one decides that, given the lack
of a better solution, the overall population is broad enough to
tolerate the imperfections since there is no better solution. To go
back to what I said in my first reply on this thread, I consider that
more about polling and statistics than voting.

I'll be happy to let it go at that, though, since we all appear to be
in agreement that there is no "magic" solution; only those that are
"close enough for government work."   :-)
