Post-college anime groups

So high schools and even colleges/universities have anime groups, but what do you do post-graduation? Anything other than conventions? I've never seen an anime club outside of an academic institution.

The only thing that comes to mind is forming a circle with people you already know or conventions/offline meetings. Keeping in touch with people. Doesn't this kind of social thing apply to anything when you're out of school? That's the chance to make connections and network, or so I've been told.
