All posts requiring a reply from your classmates before class are due two days prior to class, although earlier posting is encouraged.  All replies, and all post not requiring replies, are due by the beginning of the class session for which they have been assigned.  Post should be long enough to address the prompts fully.  I would expect most to be in the range of 200 to 300 words.  Keep the tone of the posts friendly.  Say what you have to say, but be respectful of the feelings and views of others.
