As you use Redmine and ChiliProject you’ll probably be adding more projects to keep things organized. After awhile though you’ll end up with a lot of projects, many of which are complete.
What you will want to do is to Archive the old projects. Archiving will hide the project from all parts of the system but will keep it’s data around. Archiving a project helps reduce the clutter but still lets you access the project data if you need it in the future.
To archive a project, go to Administration > Projects > and click the Archive button next to the project name. Unarchiving a project is the same process, just use the Unarchive button instead.
