PRE HTML element on this website

John, I'd recommend adding the <pre> element into the allowed HTML for the site and stop the bad use of stlyes you've got on <code>

<code> is for inline text, so I could put a short snippet of code in the middle of a line of text (e.g. echo "test";) and <pre> is for big blocks of preformatted text:

This   text   has   lots of   spaces in it,
but   they  won't   show properly until John
allows   <pre> elements   on his   website

I doubt it will be helpful anywhere outside this post, but the codefilter module is interesting, and it would be handy if you enabled the "recent posts"/tracker menu item - as I use that frequently.
