I know this is a noob question but. Is there a plugin for wordpress that lets users make post? My first blog is going to be a basic joke site. And i just want a simple submit joke button and to have that joke posted on the main page. Do i need a theme based for this if so whats a good one? Thanks... oh and is it possible to set this up when i add a rating system that the top rated post is located at the top of the page?
