Helios does not make a big thing of this, in fact I am not sure they tell you.
Seeing as we have new CAP members I thought I would remind everyone.
If you are CAP member and you have already submitted your vote, but for some reason have changed your mind on some of it.
Just go through the voting process again - follow the URL in the email, revote, submit the new vote and that will overwrite your previous submission with the new one.
Only the last submitted vote counts.
