All library staff have been subscribed to ulms-announce@lists.calstate.edu. This is a "push" only listserv, where the implementation team send announcements for the project.
Each campus contact for the project is also subscribed to ulms-pm@lists.calstate.edu.
Otherwise, each broad area has a listserv that any interested library staff can join to discuss issues related to their functional area. All listservs are also archived and can be searched.
