WP Voting

Site owner to add voting functionality to the blog posts.

Idea Factory was born out of necessity, and the frustration of the lack of plugins that did exactly what I wanted it to do. This plugin allows users to submit new ideas from the front-end, and vote on them. Currently it allows a user to vote once per idea, then locks them out. It’s also currently limited to logged in users, for now.
<ul>
<li>AJAX powered front-end submission and voting</li>
<li>Works for both logged in and logged out users</li>
<li>1 vote allowed per user per idea</li>
<li>Emails the admin of a new submission</li>
<li>Automatic setup or use anywhere with a shortcode</li>
<li>Optionally set a threshold where each idea will be given a status based on total votes and emails the admin</li>
<li>Automatic status grading</li>
<li>Extensible with hooks and actions on events</li>
<li>More ideas loaded with AJAX on front-end</li>
<li>Mobile friendly</li>
</ul>
