LDraw.org Steering Committee
The LDraw.org Steering Committee, sometimes abbreviated as SteerCo, is a group of people which get elected on a regular basis.
These people steer the direction into which ldraw.org is moving.
Note that that is something different than dealing with technical specifications. These instead are taken care of by the LDraw.org Standards Committee.
