I have an idea for a poll. I filled out the title field and then I put in some text, posing my question. I uploaded a photo. I hit "post". I got a red box that said something like: "You need at least two options" I don't know how to set this up and I see nothing that explains how. It will be basically a yes or no answer, maybe a third option "no but I'd like to". Can someone please explain or point me to a "How to do a poll" reference?
