Getting emails of petition signee

[Thomas Perissino]

Hello Change, 

We are an organization and would like to set up a campaign allowing us to request the signatures on it. 

We need very clear answers on the following questions : 

• Is it possible to get the signature while the campaign is still running or are they available only when it's finished? There is no clear info about that in the documentation. Actually, we NEED to contact the signee during the campaign because we'll have to make them sign a legal document. So please be cristal clear in your answer. 
• What is the structure of the csv output? Could we have a full example of this? 
• Can we have accurate screenshots of the different steps that have to be fulfilled by the organization AND by the signee to allow the email address to be collected?

We tried to get an answer to this through the contact form and through facebook messenger with no constructive reaction for the moment. 

It's of the utmost importance to have these infos before moving forward and using change.org for good. 

Thanks for your help.
