The bracket assembly of claim 1, wherein the integral structure includes first and second flanges adapted to be fastened to the platform. 3. The bracket assembly of claim 1, further comprising a gear mechanism for shifting the first and second drivers. 4. The bracket assembly of claim 3, wherein the gear mechanism includes first and second driver gears threadably connected to the first and second drivers, respectively, and an actuator gear coupled to the actuator assembly, the actuator gear engaging the first and second drivers gears. 5. The bracket assembly of claim 4, wherein the actuator assembly includes a reversibly rotatable knob for shifting the brace member between the support member engaging positions and the support member clearing position. 6. The bracket assembly of claim 4, wherein a gear ratio of the first or second driver gear to the actuator gear is between approximately 1:1 and 3:1. 7. The bracket assembly of claim 4, wherein the gear ratio is approximately 15:8. 8. The bracket assembly of claim 1, wherein the support member engaging surface of the brace member is adapted to conformingly engage the support member. 9. The bracket assembly of claim 8, wherein the support member engaging surface of the brace member includes a plurality of spaced-apart cross surfaces. 10. The bracket assembly of claim 1, wherein the bracket sleeve is fixedly coupled to a platform. 11. The bracket assembly of claim 1, wherein a distal end of the actuator assembly defines a faceted surface adapted to conformingly receive a retainer, the retainer substantially resisting decoupling of the actuator assembly and the brace member. 12. The bracket assembly of claim 1, wherein the brace member includes a support member stop for limiting travel of the support member within the bracket sleeve along the bracket sleeve longitudinal axis. 13. A method of assembling a portable stage, the portable stage including a bracket assembly coupled to a platform, the bracket assembly adapted to receive a support member presenting a support member longitudinal axis along a bracket sleeve longitudinal axis of the bracket assembly, the method comprising: positioning a brace member into a support member clearing position, the brace member having a support member engaging surface and spaced-apart first and second drivers;inserting a proximal portion of a support member into a bracket sleeve;substantially aligning the bracket assembly longitudinal axis and the support member longitudinal axis;simultaneously shifting the first and second drivers;positioning the brace member into a support member engaging positing by pushing the support member engaging surface of the brace member against the support member;operating an actuator assembly to rotatably engage a gear mechanism, the gear mechanism including first and second gears, the first gear threadably coupled to the first driver and the second gear threadably coupled to the second driver. 14. The method of claim 13, further comprising: positioning the brace member into the support member clearing position by retracting the support member engaging surface from the support member; andremoving the support member from the bracket sleeve. 15. The method of claim 13, further comprising: utilizing a mechanical advantage to position the brace member transverse to the bracket sleeve longitudinal axis. 16. The method of 13, further comprising: limiting travel of the support member within the bracket sleeve along the bracket sleeve longitudinal axis. 17. A bracket assembly for detachably coupling a support member to a platform of a portable stage, the support member presenting a support member longitudinal axis, the bracket assembly comprising: a bracket sleeve presenting a bracket sleeve longitudinal axis, the bracket sleeve adapted to receive the support member, with the support member longitudinal axis and bracket sleeve longitudinal axis being generally aligned;a brace member shiftably carried by the sleeve and shiftable along a path of travel transverse to the bracket sleeve longitudinal axis between a support member engaging position and a support member clearing position, the brace member including a support member engaging surface and spaced-apart first and second drivers;an actuator assembly for simultaneously shifting the first and second drivers to push the support member engaging surface of the brace member against the support member when the support member is received within the bracket sleeve and the bracket member is in the support member engaging position; anda gear mechanism for shifting the first and second drivers. 18.
