Title doesn't change when I add new words

[dereksdomain]

Hi!

I was wondering what the problem is with the title of my homepage at http://www.videogameauctions.com

Currently, when you look at the top of the webpage, the "title" says:

VideoGameAuctions.com | Showcasing Rare Video Game Auctions & Game Collectibles

The problem is that a month ago I went and revised this, but the revision hasn't taken place. It still shows the old "Title". Where I went to revise this title was in my "Dashboard" and clicked on "Settings". In "Settings" I revised it under "Site Title" which says:

Video Game Auctions | Showcasing Rare & Interesting Video Game Auctions

This version above is the one I would like as the title but doesn't seem to appear :(. I checked on both Firefox and Explorer in which they yield the same result (how I feel).

Any help would be greatly appreciated!
