"We-Subjectivity": Husserl on Community and Communal Constitution

I experience the world as comprising not only pluralities of individual persons but also interpersonal communal unities – groups, teams, societies, cultures, etc. The world, as experienced or "constituted", is a social world, a “spiritual” world. How are these social communities experienced as communities and distinguished from one another? What does it mean to be a “community”? And how do I constitute myself as a member of some communities but not of others? Moreover, the world of experience is not constituted by me alone, nor am I myself the final arbiter of what is true or false about it, of what is good or bad about it, etc. Constitution is an intersubjective achievement: “we” – I with others – constitute the world. Thus, the world is not only constituted as including interpersonal communal unities, but it is also constituted by these communities: groups, teams, societies, cultures, etc. are themselves "we-subjects”, Husserl says, communally constituting the world of their common engagement. But what is communal, as opposed to individual, constitution and how is it achieved? And what sense is to be made of the notion of plural, collective, "we-subjects", communally constituting a common world?
