Majug², the Mannheim Java User Group, was founded in 2008 and offers regular talks on Java-related topics about once a month. Every now and then we hold a CodeCamp to hone our coding skills and get to know a new technology. The meetings are usually held at the Mannheim University, after the talk, we have drinks and socialize in a nearby pub. Members come from all around Mannheim from an area which stretches from Karlsruhe to Walldorf, Darmstadt, and Frankfurt.
Please note that our main website is http://www.majug.de and we only use Meetup as a secondary site.
