Hello
Is there an easy way for a user to share his surveys with another user?
Which kind of permissions does he have to have?
Could anyone explain the process?
Thank you very much!

Under Survey properties --> Survey permissions, you can add users for the survey and assign them various permissions.

First of all, thanks for your response.
However, acting the way you say, you can only assign permissions on one survey.
I am asking if there is a way for a user to share ALL his surveys with another one, instead of assigning the permissions of his surveys one by one.
I mean, If a user A has 50 surveys, can a user B get permissions over them? Does user A have to do anything? Is it a matter of the administrator?
Thanks

Not actualy,

You can put a feature request.
