I am new to the whole chat room, posting stuff, but I was wondering:  How different is the UK version of HP versus the US version?  I live in the US, and only have the US version.  I don't even know where to go to get the UK version.  Am I missing a lot by reading the US version and not the UK version?  I've been reading the posting on this site and notice often how the UK version seems to explain more.  Is that true?
