Amsterdam Web Communities System
Amsterdam is a system allowing for the hosting of multiple virtual communities, each with services such as conferencing. A user on an Amsterdam site may join multiple virtual communities on that site.
Why "Amsterdam"?
The first implementation of this concept was in Durand Communications' CommunityWare software, which was code-named "Rome" when it was in development. Rome was a center of community in the ancient world.
The second implementation was the Java code I wrote to rescue Electric Minds; I named it "Venice," which was a center of community during the Renaissance.
This new implementation is named "Amsterdam," which was a center of community during the Age of Exploration, in particular, the Dutch Golden Age.
