Correct, you won't see it again. Your clicking of the dismiss box is linked with your user ID in the database. The only time you will see it is if you have not yet logged in.

The box is a standard "Notice" in the vBulletin software so it was much easier to set it up using that rather than separate code to make something smaller and snazzier.

My understanding is that you only need to inform visitors and gain consent if cookies ARE used. If they aren't used you don't need to do anything. Although a single line message does no harm, and shows you have taken suitable note of the legislation. If you use any sort of third party visitor statistics (such as Google Analytics and even some hit counters) they will use cookies. However the statistics provided by the hosting company (such as Webalizer or Analog) that do not need code adding to the page don't use cookies.
