If you have questions, you should post on Piazza or come to our office hours. As a general rule, use Piazza rather than email, as that helps us manage communications among the staff. Piazza allows private posts that will only be seen by the poster and the staff. Of course, if your question is of a personal nature that should only be directed to Professor Fisler or the HTAs, feel free to email us directly.
The Course Missive contains more detailed guidelines on contacting us.
Emailing cs0111headtas@cs.brown.edu will reach the HTAs and Professor Fisler. cs0111tas@cs.brown.edu will reach all of the staff. Please mail the entire TA list only if you don't have access to post on Piazza.
