Okay, there's usually a post to that effect every Friday. Click on the post and scroll to the poll, choose your preferred nominee and then, click on vote. Comment on the post to indicate your participation.
I hope I've answered your question? Also feel free to ask for more clarification if any.
Friend, I click on the person on the list but it takes me to their profile, I don't see where it says "vote"
Don't click on the person's profile, click at centre , on the name of the nominee
When you click on any of the nominee you want to vote for, It should enable the vote button, then you click on it
