 ## New projects
 
 We are also open to working on or hosting projects that are related to the Creative Commons licenses or general mission. Our [Google Summer of Code project ideas](/gsoc-2019/project-ideas) list is a good place to find ideas we'd like implemented. If you're interested in working on one of them, please propose it in one of our [community forums](/community) (you don't need to be a student, anyone is welcome to work on those ideas) and work out implementation details with CC staff members before you write any code. If you want to suggest a new project idea, follow the same process.
