All my code is written against 1.0.2 SVN, so it’s not 0.9-only and yeah, $allowed_tags is meant to be changed and then back again, not the cleanest way of doing things, but it should work. The copy that’s working live at the moment is below (I just realised I forgot to turn on the validation code too, oops):

<?php
