I guess that because the owners of the site are from the UK (or were when it was first set up) we introduced it to our friends and family first, that in turn meant that those people passed on our site to their friends and family and we have ended up with a majority of members based in the UK.
Since then we have and continue to work hard at getting Pixalo listed in the serach engines and known on the web. This is now beginning to pay off and we are seeing new members joining from all over the world. We currently have members from China, India, NZ Aus, USA, Canada, Brazil, etc etc
Most of our traffic actually comes from the USA and not GB as most would suspect. However it seems our most vocal members are based in the UK
