Re: [phpesp-dev] What affect would it have if we were to allowactive surveys to be modified in that

[Charlie S. <Sm...@ld...>]

I guess we don't much care about skewing the results, as the purpose of the
survey would be more just to collect information and give a static, pretty much,
set of results with no analysis.

Off the top of my head...

If the question you add is not a required question, and you want to be able 
to see how many people chose to answer that question,  you would need an 
"effective date" representing the date that the question was added, in 
order to be able to distinguish non-responses from respondents who 
submitted a survey before the question existed.   Seems like that column 
would need to be added to the 'question' table.You'd then need to modify 
the Admin pages like "View Survey Responses" so that they take this into 
account.
