Request about opinions

[godix]

I just did an opinion where I must have misclicked and ended up not marking one of the catagories I thought I did. When I clicked done the system accepted it and threw me back to the 'my opinions given' screen without cautioning me that the opinion wasn't accepted. Fortunatly I'm in the habit of scanning through my given opinions to see where the new one ranked and equally fortunately I'm running firefox which keeps form data when you click back, otherwise the entire length opinion would have been lost. If an opinion is submitted which won't be accepted because a catagory isn't marked could it throw up an error page clearly pointing out what was wrong instead of acting like it was accepted?
