Oh. LincDoc is not a Laserfiche product, it's a custom application. So you might have to call up your reseller and ask for more details. However, as far as I know, those are Laserfiche metadata fields.  You can look at them in the Laserfiche Administration Console. For list fields in Laserfiche, there are 2 options: static lists or dynamic fields. If it's a static list, you would have to add the new user yourself and delete the old ones. If it's a dynamic field, the Admin Console will point you to the SQL table where it's getting the values from. Then you'd have to track down how that table is supposed to be updated. This part is completely outside of Laserfiche.
