I know this would end up heaping more work upon vroom, but this is an excellent idea, and overall,
would cut down the number of nodes that have to be edited because of someone not using < CODE> tags
It wouldn't be that hard probably. vroom could just remove <PRE> from the Perl Monks Approved HTML tags. Then they would be automagically deleted at least. It would probably be a good idea anyway to extend the filtering functionality to give a warning about the use of unapproved tags, instead of just deleting them without explanation.
