General questions :

1. How to put shoutbox on . . .?
You have to create the shoutbox (first get an account here), then specify some desired settings and paste the generated code to your website. It is really that easy and if you happen to have any problems, just let us know, and we will figure it out :).

2. Is it possible to moderate shoutbox?
Sure, it is possible. Just sign in, and then go to 'Your shoutboxes' -> 'edit shouts' and delete some shouts. You may also ban people with certain IP so that they can not access the shoutbox.

3. Show me different settings!
OK, just follow this link: different settings and demo.
