What is WordCamp?
According to WordCamp Central,
WordCamp is a conference that focuses on everything WordPress. WordCamps are informal, community-organized events that are put together by WordPress users like you. Everyone from casual users to core developers participate, share ideas, and get to know each other.
WordCamps are not-for-profit events that grow out of the local WordPress communities. In Atlanta, our community is made up of people that are active in our local WordPress Meetup Groups.
