Change an updated site to another listing

I know that it seems that this question has been asked before, but, actually, I couldn't find any answer.
My problem is:

Two years ago, I submitted a site and was placed in the right category. (Movie Reviews). Now, I've changed my website and I think it suits better in Capsule Reviews.
What should I do? Who do I notify? Should I submit it again?

Sorry if this has been asked before, but, honestly, I couldn't find any solution.

Thanks.

Go to the category where your site is currently listed, look for the Update URL link and submit an update request asking that your site be moved.

Free tip! Don't try to take advantage of the move request to keyword stuff your title and description, as the move request might get lost when the rest of the update is being trashed.
