InaSAFE is a new project. The current code development started in earnest in January 2012 and there is still much to be done. However, we work under the philosophy that stakeholders should have access to the development and source code from the very beginning and invite comments, suggestions and contributions. See our milestones list and our open issues list for known bugs and outstanding tasks.
