My site has been listed in Y! for 3 years, orginally as a free submit. Persuant to my content updates, I recently used the change form to request one additional word added to the existing description. Two months went by with no response, so I requested the update via the url-support email address.
Well today I did see a response. Nothing has changed in my site description, but but it has now dropped from PR #4 to #48.
Wish I had never said anything!
