Fully and correctly linked currently means:

• the name is not linked
• the base monster (if applicable) is linked as well as any templates or classes
• the type and all subtypes is linked (with anchors)
• all skills and feats are linked
• all special senses, abilities, attacks, and qualities that are not described in the monster entry are linked (common ones like immunities don't need to be linked)
• all spells and spell-like abilities are properly linked
• all bolded sections are NOT linked (eg Str, Dex, Con, CMB, CMD, SR, or Spell-Like abilities should not be linked in the stat block)
• all AC modifiers are linked
• the tactics section is not linked (italics should still be inserted as appropriate)
• the first instance of each term should be linked in each paragraph of description - ie if the word "grapple" occurs 10 times in the description of an ability, the first instance should be linked, but the other should be removed... this makes things less a sea of links and more readable
