You export items as .erf files and then zip them using Winzip, then email them to Ziroc (click on his name above). He should then be able to unzip and import them into the mod if he chooses to.
To import, there's a function called Import in the File menu, point it to whatever .erf file you want to import (I would suggest creating a folder called Custom Content or otherwise put these .erfs into your HakPak folder) and follow the instructions.
Z's making some adjustments to the Undermountain mod I would imagine - I want it to be online too!!
