  We summarise the main results on the faint submillimeter (submm) galaxy
population which have come from the SCUBA Cluster Lens Survey. We detail our
current understanding of the characteristics of these submm-selected galaxies
across wavebands from X-rays to radio. After presenting the main observational
properties of this population we conclude by discussing the nature of these
distant, ultraluminous infrared galaxies and their relationship to other
high-redshift populations.
