How can a guest view the “Pending Review” Post?

1. When a user creates a new post it will have “pending” status. So I want the visitor (guest – not logged user) to be able to view “Pending” posts and vote it to “Publish” if enough “X Votes”. Google bot can also crawl “Pending” Posts.

2. I want to use permalink for “Pending” Post.

How can I do this?

Please help me! Thanks all friends!

The best way to do that is with this plugin:

OF course you can dig into it’s source code to try to implement the core functionality if you prefer, but I use that plugin on several active sites with success.
