Could take some work to determine the number of entries, but some sort of loyalty bonus or leaderboard, out of the 100 weeks who has had the most entries...
Or maybe we all need to drink 100 beers each.
Or tell you which of the beers we have drunk for Beersaturday has been the best.
Whatever you go with 100 weeks is an amazing achievement - thanks for all the effort @Detlev.
