I have a wordpress site at...
I would like everyone to be able to edit a page the same way people can edit a page at wikihow.com
For example if you take a look at some of their articles, for example..
You can see that you can actually edit a page without being signed in. Now, the changes that anyone would make after editing a page are instant but in my case, for yupedia.com, I would like to be able to see the changes that have been done for each article, and review it and approve or disapprove it.
Is there someone who knows how to do that? Is there a plug in for this?
