I am testing a mod here on the den sections only that shows item stats in a little popup. so testing :

[item]19019[/item]

[item]Thunder Lizard Blood[/item]

you can put items from wow in [ item ]xxxx[ / item ] tags

xxx can either be an item ID from http://wow.allakhazam.com/db/itemlookup.html?x or an exact item name from ingame. ofcourse you will put no spaces when using it, I put spaces in [ item ] so it wont use the code. also you must click on the item once after making the post to activate it.
