For this it is necessary to save participants mail address. To provide anonymity I want to save their mail address without their subject number, so there is no link between the mail address and the rest of the data. Is there any possible way to do this?<br/><br/>Thank you!<br/><br/>Jakob.Sun, 03 Apr 2016 11:49:02 GMTCoatihttps://forums.millisecond.com/Topic18754.aspxYou can run a separate script after your "main" script (via &lt;batch&gt; for example) that does not save the subject id to its data file (use the &lt;data&gt; element's /columns attribute to only specify the data you want).<br/><br/>That, however, will not fully disassociate the email address from the subject id, because the id forms part of the data file name (this cannot be changed). <br/><br/>Alternatively, redirect your participants to some other site / web form under your control and have them enter their email address there. In this case, there would be no associate between their subject id and their email address.<br/>Sun, 03 Apr 2016 11:49:02 GMTDave
