The problem with actually joining social groups is that when they get large enough they require a 'secretary' to keep track of what the group has decided: the rules the minutes etc. Unfortunately when one's members are shall we say older there is a need for actual documentation of meeting proceedings printed out on actual paper. (FYI I'm VERY much in favor of paper documentation.) These page dividers are excellent for making it easier to find the specific bylaw or note or minutes quote before one's board members come to blows.
