For those who have never heard of this addon it's a Warcraft addon that, when your queue is ready in Dungeon Finder, it makes a sound that is heard even if your doing something else such as browsing the internet, or checking your e-mail. As you can imagine this addon will be the end result for not missing another dungeon, or more appropriately, not getting kicked out of a group because you took two minutes too do something else.
Also, for reference, here is a link to the addon I was talking about, this way for those of us who play Warcraft, you'll have a better chance to understand what I'm talking about.
