    As the winner, I decided to see how I had been able to achieve this
    exalted honor. I reviewed my postings this month and figured it out.
    On two occasions I wanted to add small attachment to suppliment my
    previous posts but I did it by replying to the existing emails that
    already had large attachments so those large attachments were sent
    around a second, un-needed time. I will watch this in the future.
    
    Some other groups I post to have a "files" section on the site to
    which I send the attachments which are then just referenced in the
    actual post and members are free to go to the "files" section and
    download only the attachments which interest them. Does google groups
    have such a system?
