Update: 4 Dec, 2009 - Thanks for the help so far. If you are seeing "There was an error with your submission. Please make sure you are actually logged in." as a guest, I am working on it.I have worked with @DISQUS to resolve some issues with DISQUS comments on the site. I am trying to find out from people that have been having problems if it is any better. So if everyone could please try and leave a comment here for testing, it would be appreciated.
