What is the code to join the challenge?

All Challenge Hound challenges are private by default and accessibly only through privately shared links. Codes can also be added to any challenge by the challenge administrator to further prevent uninvited participants from joining. If a code is added, participants will need the private link AND the private code in order to join the challenge. Codes can be changed at any time by the challenge administrator. 

If you are a participant, you will need to contact the challenge administrator for details related to the challenges, like codes, private links, entry fees, start dates, and activities allowed. Challenge administrators manage these parameters.
