I have just been contacted bij de Gemeente Den Bosch. On June 21 from 1-4 PM the city (Gemeente Den Bosch) has organised a "Market Place"for newbies (and oldies).
Aim of this marketplace is to inform you on possible activities and groups in Den Bosch for example language courses, Dutch culture, and societies, tax systems (belasting), legal requirements and much much more.
There are even free snacks:-). The event is for free and you can just walk around and get some updates on the various possibel activities/groups around and in Den Bosch.
This is a very nice initiative. Settling in a new town and sometimes in a new country is not that easy.
So, if you have time, just drop by between 1-4 PM.
I will be there the whole time.
