[SOLVED] Hidden project

Best is to allocate all users to given projects with profile that removes all rights (even read right), we call this profile "no access right"
If you have many projects, you can gather them under a single one (the parent). Allocate all members to parent with proifile "no access right", and move projects to hide under this parent.
You'll just have to allocate team member to a given sub-project to give him new rights (project leader profile for instance)
