I've been thinking this through for a while and the suggestions have come from all sides that it would be a good idea to better split these forums. As such we now have distinct sub forums for items for sale and wanted for the UK & ROI, Continental Europe, Global/Rest of the World, USA & Canada and Australia.
These categories were based on the volume of posts already present. It's not perfect, but it's the best fit for now.
This means you can subscribe to a forum in your area and not be "bothered" with the other traffic.
I am slowly moving older posts into the right place. As the most posts are from North America, then I will leave everything in there that has been posted as either USA, Canada or unspecified.
