I still have mine from 2011:
http://blockland.basically.gg/Script_ItemRandomizer.zipThe first time the add-on is enabled it'll set up the following files:
config/server/ItemRandomizer/
primary.txtconfig/server/ItemRandomizer/
secondary.txtconfig/server/ItemRandomizer/
melee.txtconfig/server/ItemRandomizer/
misc1.txtconfig/server/ItemRandomizer/
misc2.txtPut the uiName of the items you want for each slot on their own line (can be done while server is running).
