Here's some mad drama concering the Nihilum guild...

Lewt, an undead priest who spent two years in the guild before quitting WoW, claims that Nihilum purposely exploited a bug on their world first Lady Vashj kill (instead of an accidental bug that took away HP, as the guild states.) According to Lewt, you can purposely wipe at 20 percent and have a paladin use Divine Shield, which I don't really understand unless Lewt actually meant Divine Intervention. Then Vashj will reset to Phase 2, but since her HP is connected to the pillars she has, the HP will disappear when they despawn. This leaves her at 1 HP. Presto, a priest pops a soulstone and Shadow Word: Deaths her, and there you go. Lewt even provides a screenshot of him finishing off Vashj with an SWD, complete with chatlog. 

Here's how to fly on your flying mount and still be able to use all your abilities and spells! Pretty cool.

Might've heard of it before, but there's a way you can fly around without a mount, but use all your abilities and stuff still. You get on your flying mount, sit on the ground. Have a mage frostnova you then immediately sheep. Then the mage casts a frostbolt and as the frostbolt goes off uses CoC. You hold down space bar while you're sheeped, and you take off. Its pretty fun, and the best part about it is you still use all your abilities. Its cheesy as hell, but it makes for an hilarious ganking session, especially for casters.

The following explanation is from Chinese sources, so pardon the translation. At any rate, here's how the bug works:

When two accounts transferring gold, one account deliver all gold to other and then log off, if this account access again, the incredible is gold still exist in, definitely, the other account get the same amount of gold easily by reproducing. The mount of gold will be increased indefinitely with this way again and again.The following explanation is from Chinese sources, so pardon the translation. At any rate, here's how the bug works:
