Just got back from OpenCon which was a fabulous weekend conference on non-monogamous relationships. We have a great community of poly people around the UK.
You can also hook up with the community at this year's Polyday. It'll be happening in Bristol on the 20th of November. It's looking like it'll be some good fun. Admission is only £10 (£15 if you want to stick around for Bobbu's amazing Pansexual Cabaret)
