To use it is similar to the wowhead links I had installed back in the wow days.
To use type [ item ] id or name[ /item ] with ID or name being for example 435134 or Warlord Flamrobe in between the item tags. once done you shall have the following. (Remember only id from wardb will generate an image and stats - and NO spaces.)
[item]435134[/item]
ALso works for Quests, NPC's and Spells, just change your tags:
[spell ]id or name[ /spell]
[quest ]id or name[ /quest]
[npc ]id or name[ /npc]
PS. Please post here which forum theme you use and whether it is working for that theme, as I have currently only set it up for SMF Default - Core. (Dont want to break other themes in case they are setup differently...)
