  This document reports the first year of activity of the VBSCan COST Action
network, as summarised by the talks and discussions happened during the VBSCan
Thessaloniki 2018 workshop. The VBSCan COST action is aiming at a consistent
and coordinated study of vector-boson scattering from the phenomenological and
experimental point of view, for the best exploitation of the data that will be
delivered by existing and future particle colliders.
