I guess, that the reason there have not been too many responses to this thread is that a lot of the users here are UK based (it is a UK Forum) and, in general, we are pretty apathetic when it comes to doing anything other than the task we are trying to do! (lol)
Just check out the threads to see how many people have said if their problem was actually resolved (I too am guilty of this) or, if they have found a solution. However, this is a problem on nearly all forums and I guess that people generally want to resolve the issues they are facing and then get on with their lives.
Having a forum based in different countries could work well, as local members might be able to react to posts faster and have a better understanding of the local PC hardware and local language but, is it really worth the costs, time and effort to do this? All for one and one for all, it worked well for the three musketeers!
Is UK hardware really different to that available in the USA or other parts of the world? I know that sometimes products are given different names in different countries (The Canon D350 camera in the UK was called the Canon Rebel in the USA and they are identical) but usually they are the same. I have bought components from Japan and used them in my builds, here in the UK, with no problems at all. (apart from trying to read the install guides!)
