We have a .csv file which contains the users email address and an associated user id.
We want to be able to import this as the participants in our survey and then be able to email the users when the survey is ready to complete.
As part of the email we want the URL to include the userid so when the user clicks on the link we will know which user it was and can associate track them throughout the survey.
Any help would really be appreciated as we are fairly new to this area of Lime Surveys
Thanks for your reply.
We figured out that if we imported the participants from our .csv file we could generate tokens which allowed us later to identify the users so we decided to do away with the userid and use tokens instead.
