Community rocks
I actively engage in communities, meetups, and conferences - always ready to contribute as a speaker, participant, or supporter. I believe strongly in the power of community. I am a founding member of Windows Management User Group Denmark (WMUG.dk) and part of the team running Workplace Ninjas User Group Denmark .
The greatness of a community is most accurately measured by the compassionate actions of its members.
Being an active member is greatly satisfying. It is about contributing to and benefiting from the common good. If you need more reasons, read the 5 reasons you should join a user group post.
