Invites for the class Forum and Google Group have been sent out. If you haven't received invites (after checking your junk mail), let me know.
The class Forum, which is a Google+ Community, is used as a place for you to ask questions, post reading and topic reactions, and discuss programming. When posting to the forum, keep in mind that you may not post code for assignments. Review the academic integrity policy or talk with me if you ever have any doubt about something you are considering posting.
The class Google Group is used for class-wide email communications.
If you have questions during the semester feel free to send me email, drop my office hours, or post a question to the forum (if you feel the question is general enough to benefit others). My email is acmarrs at ncsu.edu and office hours are Wednesdays 9:30-10:30 AM in EB2 2231.
