1. Yes, db means database. Database entries are garnered from the data that we get from SOE, and newer quests/zones/mobs/items are rarely in our database before they are released live.
2. The "eq2 quest:" part is a namespace--even our database quests use it (example: http://eq2.zam.com/wiki/EQ2_Quest:Snoogle's_Presentation
-- resolves to the database entry but the namespace of EQ2 Quest is essential for that). What the namespace does is, once we do get data for the quest, allow soe's data to link up with our wiki page. If we just put the page in as eq2.zam.com/wiki/Black_Swill_for_Blackswell then it would not hook up properly. Same goes for our mobs, zones and items.
3. If something is named incorrectly (typoed quest name for example) an admin (me or Calthine) can fix it easily by moving the page to the correct name--just post here or PM us. :)
