A friend of mine over at Tübingen Progressive Americans just set up a Wiki http://bluwiki.com/go/Tuebingens_Coopfor discussing issues of economic justice and alternatives to capitalism. I have joined and already started in. The examples for things like using Tü-Taler as alternative currency and "the Smal-Mart Revolution" are going to be primarily about local doings here in Tübingen, so it looks interesting.
