The OMNeT++ Collaborations Web Wiki, hosted in Karlsruhe, is online. This is a meeting place where people can collaborate on OMNeT++ issues. Anyone can contribute using a regular Web browser. It looks like a normal Web site, but it allows (and encourages) everyone to edit the web pages and contribute their questions and input. It is simple to learn and use, and provides possibly the most powerful way to exchange and develop ideas online, in an open, uncomplicated environment.
