Once logged in and looking at all their surveys, Respondents should see:
- First, all surveys to which they've been invited (regardless of whether they've started them yet)
- Second, all surveys they have started or completed (whether or not they were invited to them).
The second item above means that respondents should never see public surveys that don't require log-in, or public surveys that do require log-in (unless they have already started those surveys).
Public surveys (whether they require log-in or not) will always be distributed by a Facilitator in some way (emails, tweets, etc.) to a targeted audience, so they should not ever be publicly discoverable (i.e. google spiders shouldn't index them).
