Although this exploit had previously been nuked on the US version of WoW, the EU version has so far failed to patch this nice little exploit.
When in a group, be it with an alternate account of yourse, 1 other player, or many, once a skinnable mob has been killed let the person who is to collect the loot start skinning first. Once the looter has started the skinning process anyone else who also begins to skin the same corpse will also gain a level in skinning, this works even if the first person finishes skinning and even loots the corpse before you finish. Any later skinner can obtain the skinned loot as long as the original skinner leaves the loot window open without actually taking the loot. This can result in low level skinners gaining skinning levels and better loot.
Again, this no longer works on the US version of WoW but has been tried and tested with success on the EU server.
