What I am terribly missing is the following.
Linesurvey is very flexible in the invitations and reminders. It is possible to change the text before it is sent. The consequence is that I can see that the mail is sent, but do not know exactly which text is sent. It would be very pleasant if a copy of each outgoing mail was sent to a cc adres. Of course it would be pleasant if it is possible to turn this feature off.
Some other systems have this feature. To me this feature would be very import. If necessary I am willing to sponsor the development.
I tried to send this idea to the "feature request" forum it, but it appears that I need another login code for this.
