Hello, i am producing model railway signals and I want to promote them via FB. I am in 3 groups where model railroading is the main topic. When I want to create an add and want to define my target groups, I only get very restricted branches e.g. cars, hybrid cars... but there is nothing like model railroad. Is there any easy way, I can define to show my adds to people who are in the 3 model railroad groups? Best regards, Andreas
