We are looking for a software solution for agile project management, and it seems that there are numerous options to choose from. Because we are just starting to use agile here, none of us has any idea of what software might be best for managing projects. We are using Trello now for basic task management, but it seems a little too simplistic for true, multiple project management.
Does anyone have any recommendations for good software for this? Ideally, it would be fairly easy to adopt and use, and not be too incredibly expensive.
