Vote2Publish is a wpMU plugin wich allows you to define a “main blog”, and then displays a vote box in every post of every other blog in the community.

When a post gets a certain number of votes it is automatically republished in the “main blog”, preserving the original author and adding a note on the top of it with a link to where it was originally posted.

*Each blog owner can customize the vote box to match to his/her theme.. or even choose not to display it.

*Ajax powered.

*Localization ready

*Comes with pt_BR translation
