environments and several newer digital technologies replaced the functionality provided by CONFER. Sites where CONFER was used In addition to the University of Michigan CONFER was used at Wayne State University (WSU), the University of Alberta (UQV), Michigan State University (MSU), and at Hewlett-Packard (HP). MSU and HP both ran MTS so they could run CONFER. A Unix version, known as CONFER U, was created by the University of Michigan's Information Technology Division and used at U-M and at the Research Libraries Group. A version for the DEC VMS operating system, known as CONFER V, was created and used at Western Michigan University (WMU). The work on CONFER U at U-M and on CONFER V at WMU was done with the encouragement of and guidance from Bob Parnes. Features CONFER provides facilities for online discussion of topics of general interest. Discussions are organized around "conferences" that focus on a topic, a group or community, or an event. Conferences may be "public" (open to anyone with an account on the host system where CONFER runs) or private (invitation only). Each conference has one or more organizers. Individuals join conferences as participants, auditors, or observers. Conferences are accessed using terminals from various locations, allowing discussion without having to meet physically or participate at the same time. As a system developed in the mid-1970s, CONFER is a text oriented, command driven system with extensive prompts and online help. It does not have a graphical user interface (but see InfoX below) or allow the display of photographs or other graphics. Within a conference, discussions are managed as a collection of items. One person starts an item by entering the item text and giving it a title, called a header. Other people can then make their own responses to the initial entry. The item text and each response is signed with the name of its author. The item's author can specify the type of responses desired. The most common type of response is a discussion response where the response is simply text. Participants can make as many discussion responses to an item as they like. Another type of response is a vote where a numeric response followed by an optional text comment is given with only one response per item per participant. And still another response type is a dynamic value vote. One can view items in chronological order, reverse chronological order, or by following
