This plugin has adds a lot to your website and I love the idea! However, I am having an issue with people being able to vote more than once on a poll. It does prevent them if they try to vote fairly quickly after the initial vote, but if they come back a few hours later, then they are able to vote to the poll. If this is a feature then I would like an option to disable it. If not, then could you look into fixing this?
Thanks in advance!
