I have a number of employees in my company who are not Salesforce users, but who have Chatter accounts. I want to use them in a picklist, available to a custom object in my system, but when I make that field a lookup on User, it only brings up active SF licence users. I'd like to tweak this somehow to allow me to show All SF and Chatter users in this picklist. Anyone have an idea of how I can do it?
Bump!
I'd really like to be able to do this as well.
