It is deeply frustrating when a post is made and the poster has forgotten to use code tags. Invariably this gets fixed pretty quickly by moderation but for a while the post can be unreadable.
When this happens I tend to look at the html source code for the page as the post is printed there as it was entered (near enough).
I would like to propose a 'Show as entered' link which would show the post exactly as entered and allow people to read the post before the formatting is fixed. This could perhaps be achieved by slapping the whole post into pre tags.
