I've noticed threads on here about commenter information not being saved, apparently because no cookies are being generated, but all the steps I've tried using to fix it on my site aren't working at all.
I have three sites with WP 2.0.3 installs on them. Two of them save commenter information after they a comment is left, one of them does not. I've tried copying wp-comments-post.php from one of the working installs to the non-working install to make sure the proper cookies are being left, but nothing. This is happening with all themes I've tried as well. The site is http://www.haveyoumettony.com, if that helps.
