After explaining the necessity for exotic hadrons, we discuss mechanisms which could account for the production of the exotic Θ -baryon. A possible important role of resonances (producing the Θ in real or virtual decays) is advanced and emphasized for selected processes. Promising experimental investigations of such resonances, and the Θ itself, are suggested. We also briefly discuss recent negative results regarding the Θ -baryon.
