• The CircleCI tests are not passing. The main error seems to be this:

rest_framework.exceptions.ValidationError: {'make_programs_available': [ErrorDetail(string='This field may not be null.', code='null')], 'make_input_data_available': [ErrorDetail(string='This field may not be null.', code='null')]}

• Also, I am wondering if make_programs_available and make_input_data_available are the best names for these variables. Maybe is_program_available and is_data_available instead?

• Edit the documentation (https://github.com/codalab/codabench/wiki/Yaml-Structure)

• Add a question mark (?) next to "Files available" to explain the role of the feature:

• Names:
  Need consensus if we like the names of the options (make_programs_available/make_input_data_available) or if something else would be best.

• Documentation:
  
  

• Checkmarks:
  

• Question Mark:
  

Qutstanding thoughts:
Should we hide the "Available" column altogether for non-organizers? It will always show a green check for whatever is available.

Awesome work!

Should we hide the "Available" column altogether for non-organizers? It will always show a green check for whatever is available.

It is not crucial, but yes I guess it would be cleaner

I rebased develop to have the recent changes (especially the migrations from #1126).
