some people do get funny about getting too many emails, fair enough, but this has been taken to the other even worse extreem - no emails ever.
as others have said the claims page is the big one that should have gone to everyone, you dont need to email every time anyone does anything (meeting to discuss X or descision due soon etc) thats what the forum or something like twitter is for. at the very least there should have been 1 email to say 'here's the claim page, for further info see this forum thread/twitter feed/website'
