This is a new idea of mine that will hopefully work out.
For each month, I will select a particular author (so that the discussion will have wider range) and start a discussion of his/her work. I will make it a sticky topic then split the thread and undo the sticky thread at the end of each month so that the particular author can be continued talked about.
Please feel free to suggest some interest authors - the only criterior would have to be that the author is more or less widely known to ensure participants.
