How do I join a project?
Only a coordinator of a project can add someone else as a developer or coordinator. The policies for joining a project are determined by the coordinators of each project, so you should contact the coordinators of the project that you are interested in joining
to determine how you can join.
To find out who are the coordinators, you can check the People tab of the project. You can contact the coordinators either by posting in the discussions section for their project asking about joining, or clicking on the coordinators name on the People tab and
selecting the Contact option.
