I disagree. I think stripping HTML from my text is a horrible thing. If
I want to put a <b> in my text, then use htmlentities() and show me a
<b> when I look at it. Obviously you don't want to "evaluate" HTML, but
the end result should be that I should see exactly what I typed into the
text box. 

If you need to allow formatted text, then use something like BBcode
where you can specify exactly what is allowed.
