I haven't looked at the code, but doesn't strip_tags strip everything b/n
< and >?  In which case it's doing what it should below...

The only solution I see would be to change the code to look for every
possible HTML tag that exists and only do those, but with all the
nonstandard tags I don't think that would work...

what happens if you put "< >" in the second argument?
