Python Community Server: Development

I've implemented Mark Pilgrim's advice on labelling form elements (day 28 of his '30 days to a more accessible weblog' series) for the comment feed here at PyCS, so now the table used to format the comment entry area should make a bit more sense when read with a screen reader.

The comment HTML (example) still doesn't validate, but it's getting there - a lot of table rows were missing </tr> tags - oops.  Anyone know how to get the width/height of the textarea right and still give the validator the 'cols' property it needs?
