Well I tested the simple vote on the profiles, it works correctly with delay = zero. But in front of your septism, I just tested simple vote on the answers forums, and there I have nothing, neither mail nor site.
So I correct, it solves almost all my problems. I understand that it is a big piece difficult to put in place.

In addition I do not have any more notifications for the mentions either, neither on the site, nor on by email, this with the delay = 0
