In Cambridge, there exist various Poly groups who openly declare themselves as such (or similar, or more generally).
At least in recent years, Polys have become more widely welcome in Cambridge :)
We thank those Polys who helped out here prior to the above good things becoming so :)
We will look into providing some links here.
For now, the UniCORNS (University of Cambridge Open-Relationship and Non-monogamy Society) have now asked to be advertised on our webpages, so here's a link :)
Our webpages' glossary will include Poly concepts, terminology and symbols. *Expected in Jan 2017*
