NOTE: To do this you likely need to have the FireFox browser, as IE is really FUBAR when it comes to many options on the Corpus.
When a new member makes their first 5 posts they will all be placed in the Moderation Queue, which can be accessed several different ways, but I’ll be focusing on the two most basic methods below starting off with the Moderation option via your User CP.
If you click into your User CP and scroll down the left hand menu till you get to the Moderation Box you’ll see three drop down options. The one you will want is Moderated Items If you click the little 
it should show a list of several items.
Moderated Items
Threads
Posts
Visitor Messages
Group Messages
Group Discussions
Picture Comments
Album Pictures
If you click on any of the links it will take you to another page that lists all of the unapproved comments/posts/threads. To start with I’ll likely only be limiting Threads and Posts, but if trolls and spammers figure out that other options are not limited we may need to expand… but for now, it’s just threads and posts (and they ARE different so BOTH need to be looked at!)
If you click on either it’ll show you a ’search by post’ for those in the queue. You can click the little box at the top and it will pick ALL of the items on the list. Or you can go through and click the second box (or the top box on each individual item)
Once the items to be approved have been selected, scroll down to just below the last item and select the drop down menu listed Moderation (it’ll show ‘Merge Posts’ as the top option) to approve all the ones you’ve checked pick ‘approve’ and then select the GO button. (it’s fancy and will show you the number you have approved next to the go, in the example I have 0 selected).
Now all of the ones you’ve selected are seen by the public eye!
But wait, there is more! Should there be a couple that you do NOT approve, start back at the beginning and rather then Approving them, DELETE THEM! This will clear up the queue so you (or others) do not need to look at them again. Though please keep in mind we are NOT the thought police! Approve all posts that are not breaking the rules… this includes dumb-assed posts you’d rather not see! Seriously… if it’s not spam, trolling, flaming, etc, it NEEDS to be approved. If you don’t like something that is said click into the post itself and give negative rep to voice your opinion… using the queue to limit what is said is an abuse of power.

The second method of approving posts is a bit more complicated, but chances are you’ll come across them.
is the spokesman for the Queue and you’ll see the little icon in several places (like in searches, or in posts/threads that are moderated. Only the mod team can see them and they are there to let us know something has been moderated. If you are reading a thread and happen across something in the queue, you can approve it just like I explained above. Click the checkbox in the top corner of the post, scroll down to the Moderation Menus and approve/delete it as needed.
In a search however, you’ll likely not get the option if the thread has a queued post in it, you’ll need to click into the thread or check the moderation page through your User CP.
