The CoCo is the committee that is in charge of the computers, servers and a lot of the digital systems that exist within Thor. They are responsible for the hardware, software and server accounts. Thus making sure the other committees can perform their task in peace.
Within Thor, the existence of a lot self-made digital systems, gives Thor and especially the CoCo the possibility to make and improve a lot of systems. This makes sure all systems within Thor are perfectly suited for the specific needs of the association and its members.
