All possible entries: activities, resources or posts in take part can be directly connected to a project. That way they get listed in the project space, while the project is always pointed out next to the content. Notifications of new entries will be sent to all friends of the project.
All members and collaborators of a project are able to create project content by referencing the project in the form. Later any project member will be able to edit project content, even if it was created by somebody else on your team.
An easy way to create project content is going to your projects space and use the links provided in the expandable ‘create content’ box. That way your project reference is already filled in the form. You can reference any of the projects you are a member or collaborator of every time you fill a form.
