Okay new implementation you can see examples below. There are 4 tags to the left of the bullet point in the message editor when posting each has it's own function.
We can now do Achievement, Item, Quest, and Spell
Usage: [item=itemid]Item Name[/item]
<== Sub in achievement quest or spell as necessary. I am working on getting to the point where you will only need to do item name. This time though the change will be backwards compatible.
