I'm using 1.91 and am trying to solve the following>
We have registered members on one site and will be passing some of the details to the questionnaire via the URL (i.e. MemberID). All works great, but I cannot see an easy way that ensures that members enter the questionnaire only once as I'm sure this cannot be done via tokens.
Tokens are the only way to ensure that user really fill out a survey only once.
There is a setting to set a cookie on survey completion but users can work around this e.g. by using a different PC or deleting cookies.
