LCA2015 will be in Auckland, New Zealand next year, and the Call for Proposals has just opened! The conference is one of the best venues in Australia and New Zealand to get word out about your Open Source project, as well as learning about the cool things that other people are doing. This is the third time the conference has been in New Zealand, and its looking to be an excellent event.
This one call for proposals covers papers, tutorials, and mini conferences.
