The click has probably atleast twice or thrice the amount of members listed here, but many of these people have never released anything by theirselves and have just rapped on Screw's tapes.
Some artists who are not "real" members of the group have also appeared on the tapes, and they are often labeled "S.U.C. affiliated." The best example of this would probably be UGK who appeared on a few mixtapes.
With the passing (Fat Pat, H.A.W.K., Big Steve, Big Mello & DJ Screw) or incarceration (K-Kay & Mike D) of many of its prominent members, the Click has gradually disbanded to a degree, as some members have moved on with their careers or affiliated themselves with other collectives.
