Each survey hosted by Papaya Polls can be set to be either
Public or Private. In public mode, anyone who learns of the
URL of your survey can respond.
In Private mode, you can enter, or bulk-upload, specific usernames
and passwords that must be used if someone wishes to respond
to your survey. This is great for surveys that are proprietary
in nature, or if you need to ensure that each person only
gets to submit a single survey response.
