If you have general questions about the contests, rules, or a solution to a particular contest, first see the discussion group. Before you enter a contest you should join the discussion group. If you have already entered, but haven't joined the group, join the discussion group now.

It is important that you join the discussion group for two reasons:

• First, it is the appropriate place in which to ask for clarification of the rules. Be aware that sometimes these requests result in changes to the rules, and the only place those changes are announced is in the discussion group.
  
  
• Second, the discussion group allows contestants to interact with each other to discuss programming techniques, results and anything else relevant to the contest.

If you have a problem using this site, accessing your account, or have a personal question about the contest that you don't think is of general interest, contact Al Zimmermann.
