I note in the FT that Kalkan belediye has a free SMS text alert service which provides information in english to anyone who subscribes. Presumably this would include all the various messages provided over the tannoy service.
I know there have been various attempts to get essential messages translated and broadcast in Uzumlu, but have no idea if this idea has been tried before. If it has then please ignore and I'll go back to sleep. If it has any potential, who would we approach?
