Comment box on site?

[Ittermat]

EDIT: Also I KNOW we have a shoutbox...If theres a way to use that again on another page with a new title that would work just as well.

How would I make a comment box/guest book area on the site?
So that it automatically uses the users login when they post?

And so that I can moderate and delete inappropriate ones as necessary.

These are the basic idea for what I'd like....except the name area is automatically their username (And possibly their avatar?) on the site..

please? XD
