On a side note, Blood of Zul'jin is now an epic quality drop as of patch 2.3.2.

GG comics
Mmolecule has a special section titled GG comics, its a web-based comic by artist Ken Harrison and published on a monthly basis. Some of them are really hilarious, especially the one about warlock and northrend (its so true :p).

Teron Gorefiend Ghost Simulator
A skilled flash developer belonging to Ferox (german guild) came up with a nice tool to ease Teron Gorefiend's learning process, he developed a simulator where players play a mini game to practice the encounter without actually wiping the real raid. To be honest, the game is harder than the real thing, but its good training.
The paragraph after this one is only needed for those who never experienced Teron Gorefiend, if you already tried/killed him, just click on the following link: Teron Gorefiend Ghost Simulator.
In case you didnt know, Teron Gorefiend is a boss located in Black Temple. During this encounter, players are receiving a debuff called Shadow of Death, "upon receiving it players will have 55 seconds to continue fighting Teron before they die and transform into a ghost. It is imperative that these people do not die in the raid, as they will spawn Constructs on top of the raid. The Constructs themselves are immune to attacks from any alive players, making it vitally important that they are killed quickly.
If you get the debuff you should run out of the fight when it has about 20 seconds left, back to the main entrance.
If any Constructs reach the raid, they will hit for about 3000 on cloth." (Bosskillers)
