Daily Tasks has a database of all known Task Bulletin Boards and the Tasks that they contain. It can not only list these, but can also check your inventory for trophy items and show which items can be turned in to complete tasks (and if one of your alts can use it).

You can also list which trophy items can't be used and can check on individual trophy items. You can even display which items in your inventory can be used by a player of a specified level.

New with version 2, you can now check which mobs drop an item or what items a mob drops (the mob list is still a work-in-progress).

Basic commands:
/dt (Lists all trophy items in inventory and their uses)
/dtu (Lists all trophy items in inventory that are usable)
/dtc (Lists all trophy items in inventory that can complete a task)
/dtx (Lists all trophy items in inventory that are unusable)
/dtj (Lists all trophy items in inventory that are junk)
/dtv (Lists all trophy items in vault and their uses)
/dts (Lists all trophy items in shared storage and their uses)
/dtl (Lists task locations)
/dlz (Lists task zones)
/dtm (lists mobs and what trophies they drop)
/dtp (Lists known player characters)
/dtp <name> (Deletes player name)
/dtr (Lists reputation codes)
/dtb (Move listed items to selected bag)
/dtw (Opens a windowed version of DT)

Option settings:
/dt gr (Toggles Great River location consolidation)
/dt nc (Toggles non-completion location listing)
/dtt (Toggles new trophy item tracking)
/dtp names (Toggles whether alt names are listed)
/dtw rep (opens a window to set rep usage)

Most commands also have optional arguments. Check the ReadMe file for a full list of commands and options.

NOTICE: When installing for the first time, be sure to follow the instructions in the ReadMe file to avoid problems.
