I guess this is a problem for any newcomer to a long running series, I found the same when I joined the Simon Scarrow message board shortly after discovering his books:
http://www.scarrow.co.uk/ Many people there talked about things that I had not read yet. It was anoying but I learned to put up with it and just came to learn either to stop reading when I found a spoiler or read on and look forward to reading it "in the flesh" so to speak when I got to the book in question.
