Perhaps you could add a field to the FORUM_FORUM table to set the forum to "no edits" and then update the code in post.asp and topic.asp to prevent edits based on that "no edit" flag.
You would also have to update the forums creation page to create a drop-down box to update the flag on existing forums.
Yeah, it is a lot of work but then you can enable or disable edits on a forum by forum basis.
