Created an idea on our Aha! Ideas yesterday from home.
When I got in to work today it was possible for me to vote once again on my own idea.
I'm using the same account but from different computers and different locations.
It is not possible to vote more than once on the same idea.
We have moved this request to our Support queue in an effort to help solve any issues that you may be running into. In regards to the specific idea, we will mark as "will not implement" for tracking purposes.
Then I guess you're wrong. Because I can vote more than once. I can vote at home and then vote again when I get to work. I use the same email/password for both connections.
So when you say it's not possible you are wrong
