Ive just made some items for Throne of Bhaal and Shadows of Amn using the IEEP editor i put them on a disk and copied them so i could test them on my brothers computer but when i got them in despite having all the properties and abilities of the item it had no description.
How do i keep the description on the item if i want to transfer from comp to comp or put it up on sorcerers.net?

This is where WeiDU comes up.
Go download it.

If you're just copying a couple of items over, WeiDU seems like overkill to me. What probably be easier is to put the items in TBG format (IEEP's Item Editor has the facility to export to TBG), and then either reimport them with IEEP or package them in an IAP-SFX (self-extracting) module. This will allow the strings to be retained.

where do i download WeiDu anyway?
