Google has just release a new Google Webmaster tool that allows you to mange your sitelinks.
What are sitelinks? They are the page links listed under some search results to more pages within your site. Not all sites will have these added.

Google will only add them to your site if they feel they are relevant to the users search and if your site structure will allow for their algorithms to find good sitelinks
Log into your dashboard and see if Google has added any of your pages to the sitelinks section. If so you are able to block any one you would rather not show. You can find the new tool under the links section of your Google Webmaster tools dashboard.
Currently the sitelinks are completely automated but they say they’re always working on way to improve them and at some point they may incorporate a system to allow webmasters input it the future.
