In the mid-1980s, a new version called EIES-2 was developed to research the implementation of group communications in distributed environments, versus the centralized time-sharing environment used for the first version. EIES-2 had an object database architecture using over 2 dozen classes and implementing a notion of activities, which was a standardized interface for implementing nonstandard functions such as polls or list-gathering. The activities concept was similar to what would be done in today's message board applications using plug-ins. The standard message-based functions were also implemented as activities. EIES-2 ran on Unix and was written in the programming languagesC and Smalltalk. EIES-2 used the X.400 database standards. Accounts were available to the public for a monthly fee of USD $75 plus connect-time charges.
Influence
In his book The Virtual Community, Howard Rheingold called EIES "the lively great-great-grandmother of all virtual communities". EIES was one of the earliest instances of groupware, if not the earliest, and some users contend it is where the term was coined. The editors of the Whole Earth Software Catalog set up a private conference on EIES where they could collaborate on software reviews from around the US. Along with serious research, there were diversions like the "EIES Soap Opera", which was a series of stories written collaboratively by the service's users. The first soap opera was initiated in 1980 by Martin Nisenholtz. Working groups from different corporations used EIES to collaborate, some working exclusively from home. EIES gave an early glimpse of the challenges of work–life balance and pointed the way toward hypertext and gamification. Notable users included Alvin Toffler, Peter & Trudy Johnson-Lenz, Barry Wellman, and Whole Earth editor-in-chief Stewart Brand, who was influenced by EIES to develop The WELL. At its peak EIES had more than 2000 subscribers from various government agencies, large corporations and educational institutions. The Western Behavioral Sciences Institute ran a private conference called the School of Management and Strategic Studies, of which Harlan Cleveland was a member. As a legacy system lacking support for multimedia or file attachments, EIES was shut down in 2000, despite NJIT's inability to locate a replacement with equivalent performance. At the time of its shutdown, EIES-2 held 6 GB of stored data, and could serve 1,000 concurrent users with an average response time of under 15 seconds.
