I've got three types of projects: idea, evaluation and recruiter.
To refer to these projects, should I use "idea project" or "ideas project".
Same question for the other types: Is it "evaluation project" oder "evaluations project"? Is it "recruiter project" oder "recruiters project"?
An idea(s) projects is a project to gather ideas. Similarly an evaluation(s) project is a project to evaluate gathered ideas. A recruiter(s) project, is a project to recruit people.
