Help with censoring?

[huts]

I'd like to know how to censor text perk rank on a forum message or a page. I've seen it done, and haven't seen anything about it on here or while making a post or in the admin control panel. I'd like it to show something like this:

"<<Warning! This information has been censored to registered users only! Please login or sign up now!>>"

Any suggestions?

To stop guests from viewing anything:

How can I show content just to logged in members and hide it from guests?

<xen:if is="{$visitor.user_id}">
This content will show to logged in members only
</xen:if>

And once again, I show my incredible ability to not search for things well enough. Thanks.
