The UK, in particular London, has a UC focused user group which meets on a regular basis, quarterly. The group is known as the Microsoft Unified Communications User group London or MUCUGL.
The last meeting was in October and I see the slides for that event are now up on SlideShare. You can see the presentations from the MUCUGL web site at: http://mucugl.co.uk/.
I just wish I could make it to the MUCUGL events – I seem to be out of the country every time they meet.
