Personally, I like the markup since it doesn't change the meaning. But this should do the trick:

In newthread.php, find my hacked like:

$postcontents=unhtmlspecialchars($message);

and change it to:

$postcontents=strip_tags(bbcodeparse2(unhtmlspecialchars($message),1,1,0,1));

I've not tested this, but it may get you what you want. If you've changed it to send out HTML email, you'll want to not use the strip_tags function.
