I don't know any UK dominated sites although I'm sure there would be some out there. I like the global feel of PC even though I know it's always going to be mostly US dominated (like recently people assuming everyone must be celebrating labour day lol). I think what hankster said is good; that the experience here is what you make it. If you are having trouble with all the US posts and that way of thinking try widgets suggestion on a social group for those in the UK so that you can connect on an extra level with what's familiar to you locally and then you still have access to everyone else at PC as well. I hope you find what works best for you and gives you good support and interaction
