Using options on an added tab on the forum edit page, you can choose to make any user group be required to have moderator approval before the post is actually displayed.
The approval process involves going to the forum summary page in the CP, where it will display the number of posts in 'queue', and then clicking on the number. The following page will tell, the poster, their ip and the date it was posted. It also gives an option to open and edit the post as seen fit.Demo:

This is still a beta script, so please make a back up before modding. A future update will include the ability to PM the author for whatever reason.
Any criticism is welcome.
